ESP32-CAM WROVER E

In diesem Beitrag möchte ich dir eine weitere ESP32-CAM vorstellen und zeigen, wie du diese programmierst.

Eine ESP32-CAM habe ich dir bereits im Beitrag Einrichten der ESP32-CAM und erster betrieb vorgestellt und auch gezeigt, wie du diese in der Arduino IDE programmierst.

Bezug der ESP32-CAM WROVER DEV

Die mir vorliegende ESP32-CAM habe ich recht günstig über aliexpress.com für knapp 7 € zzgl. Versandkosten erstanden. Du findest die coole ESP32-CAM auch auf amazon.de für knapp 35 € als Set mit diversen Sensoren / Aktoren. Lieferumfang Zum Lieferumfang der ESP32-CAM gehört neben dem Mikrocontroller noch ein kleine 66° Kameralinse vom Typ OV2640.

Anschluss der ESP32-CAM

Der Anschluss an den Computer erfolgt über eine Micro-USB Schnittstelle. In meinem Fall war kein passendes Kabel dabei (jedoch im verlinkten Amazon Produkt ist es enthalten). Im Geräte-Manager von Microsoft Windows 10 wird der Mikrocontroller als "USB-SERIAL CH340" angezeigt.

Programmieren in der Arduino IDE

Das ESP32-CAM Beispiel aus der ESP32 Bibliothek beinhaltet eigentlich auch die Konfiguration für das vorliegende Modell, jedoch ist das Kompilat 10 % größer als der verfügbare Speicher des ESP32. text section exceeds available space in boardDer Sketch verwendet 1431461 Bytes (109%) des Programmspeicherplatzes. Das Maximum sind 1310720 Bytes. Globale Variablen verwenden 65344 Bytes (19%) des dynamischen Speichers, 262336 Bytes für lokale Variablen verbleiben. Das Maximum sind 327680 Bytes. Sketch too big; see https://support.arduino.cc/hc/en-us/articles/360013825179 for tips on reducing it. Fehler beim Kompilieren für das Board ESP32 Wrover Module. Auf der Seite https://freenove.com/fnk0060/ findest du eine ZIP-Datei mit allem, was du benötigst, um den ESP32 CAM vom Typ WROVER E zu programmieren und unter anderem ist dort auch eine komprimierte Version enthalten. Zum einen hat der vorliegende Mikrocontroller kein SD-Karten Slot und somit benötigen wir diese Konfiguration inkl. Bibliothek nicht.

Webinterface

Bevor du das Beispiel aus dem Ordner "Freenove_ESP32_WROVER_Board-mainCSketchesSketch_05.1_CameraWebServerSketch_05.1_CameraWebServer.ino" auf den ESP32 speicherst musst du lediglich die SSID & das Passwort von deinem WiFi Netzwerk eintragen. const char *ssid_Router = "********"; //input your wifi name const char *password_Router = "********"; //input your wifi passwords Während des Uploads musst, du, wenn die Ausgabe mit den vielen Punkten erscheint die Taste "EN/RST" betätigen und der Upload wird ausgeführt. Nachdem erfolgreichen Upload kannst du im seriellen Monitor der Arduino IDE die IP-Adresse des Mikrocontrollers ablesen. Über diese IP-Adresse kannst du das Webinterface erreichen und einen Stream deiner ESP32-CAM betrachten und auch Bilder speichern.

Vergleich mit dem Vorgängermodell

Wie bereits erwähnt habe ich dem Vorgängermodell bereits einige Beiträge gewidmet und auch gezeigt, wie du die Bilder / den Videostream per Python abgreifst und speichern kannst. Da das neue Modell sehr ähnlich funktioniert, kannst du die Beiträge auf den Mikrocontroller adaptieren.

ESP32-CAM Modelle Was zunächst auffällt ist, das die neue ESP32-CAM ohne SD-Card Slot und LED Blitz daherkommt, jedoch bietet diese deutlich mehr GPIO Pins und somit kann man diese recht einfach nachrüsten. Zusätzlich bietet die neue ESP32-CAM vom Typ WROVER E einen onboard FTDI Chip CH340 welcher durch die vorhandene Micro-USB Buchse ohne ein zusätzliches, externes FTDI Modul t die Programmierung ermöglicht. Beim Vorgängermodell wurde dieses mit einem speziellen Board gelöst, auf welches der Mikrocontroller gesteckt wurde.

Tree moisture meters

I had an interesting time last week attending the 4th Trees, People and the Built Environment (TPBE4) conference run by the Chartered Foresters.  Some interesting sessions and worthy sentiments but I didnt get any sense of urgency. 

A couple of the sessions addressed the use of technology in the urban forest.  For example Nadina Galle talked about the Internet of Nature and the application of Smart City thinking, a city-wide network of sensors using AI to make better decisions about deployment of resources.  GreenCityWatch have developed tools to create an inventory of urban trees using commercial high-resolution imagery and some open-source image analysis tools.  Treemania aims to provide a network of moisture sensors to alert council staff to the need to water newly planted trees.   

I have a love-hate relationship with these ideas.  On the one hand they too often seem like expensive, irrelevant and authoritarian structures, all bright and shiny to lure unsuspected city councils desparate to show they are doing something towards the climate emergency.  On the other hand, I’m a bit of a geek and love the idea of sensors to bring the life of trees to wider notice.   Moisture sensors also fit well with a planned platform to assist citizens to look after new trees, in particular 590 trees being planted in deprived areas of Bristol, part-funded by the Urban Tree Challenge Fund.

Treemania’s sensor seemed from the pictures to use a common capacitive moisture sensor. I thought a remote sensor could be based on a board I’ve planned to use on the boat for remote sensing of water level and battery state.  I’ve also been looking at it as a basis for a remote dendrometer. The board is an ESP32 with integrated GSM module, costing £15 or less.  GSM (2G) is expected to continue to be supported in the UK through to 2025.   Rui Santos has a great tutorial on using this board with Arduino code for just such a project.  A capacitive soil moisture sensor costs a few quid, a temperature sensor likewise.  The board has an integrated socket and charger for a 3.7v LiPo battery.  In use the sensor will only need to report at a very low frequency - maybe only a few times a day, and with the ESP deep sleep mode the device should run unattended for a month or more. Soak testing is underway.

Acquiring a suitable SIM is challenging.  Although mobile internet on a pay-monthly contract is down to £1 a Gb, minimum payment is around £10 a month. Given that only a Kb or so is used for a single  HTTP GET to transmit the data, the device needs only a few Mbs a month.  I found a couple of companies  specialising in IoT connectivity. The cheapest is ThingsMobile, based in Milan and the cost is more like £10 per annum.  Even here, the cost per Mb is 100s of times more expensive than your regular Pay monthly  sim.  It took ages to arrive but works fine and at E0.12 / Mb is pretty good.

So the bill of materials is:

TTGO T-Call ESP32 SIM800L board   

Capacitive Moisture Sensor

DS18B20 Waterproof Digital sensor

3.7v LiPo

waterproof container

Overall cost for the components should be under £40. 

Wiring is straightforward:  The moisture meter needs 3.3v power and an A2D pin  (ADC0) ; the thermometer is a one-wire interface needed a digital I/O pin (Pin25)  with a 4K7 pull-up resistor.  Rui also has a great tutorial on interfacing this sensor.  I got stuck for a while on this, not realising which GPIO pins supported I/O.  Accurate pin-out diagrams and the datasheet for the right variant of board are essential.   A small auxiliary veroboard wired directly to the ESP32 board handles these connections.  The ESP32 board is supplied with a simple aerial which worked fine.  A better quality aerial costs a few quid.

This is the current lashup

Rough sketch of wiring:  R is 4K7 

The Arduino script hard-codes the GPRS parameters, the HTTP parameters to use GET to send the data to the server and the sleep interval.  This code is on GitHub 

Periodic readings are sent to my server where they are logged and graphed and from where alerts can be generated.   A test harness only at present so nothing worth sharing yet.

Summary

The prototype is working.  The moisture sensor needs good waterproofing and seems a bit sensitive to placement.  The power draw of the GSM is quite high high during transmission.  I’m also running a WiFi version and of course its power draw is much less.    It would be nice if the Bristol LoRaWAN network was up and running but that seems to have gone very quiet. 

The main problem is with power.  This board includes a (very small) JST connector for a LiPo and a charger,  For a while it switched happily from USB power to battery and back without manual intervention.   LiPos are small and expensive however and I’m currenly experimenting with 18650 batteries which offer better storage/£ .

ESP-WROVER-KIT-Vb

Internet technology is progressing at a fast rate in the modern era. More innovations in this domain are expected to advanced the feature of IoT devices. Discussions surrounding the internet reveal that it is a  connection between different computing devices to receive, analyze and share the data. Most of the time desired results are unachievable but, researchers aim to find a balanced approach. ESP-Wrover-Kit is an innovative device the allows this to occur. What are the functionalities of ESP-Wrover-Kit? A development board, the ESP-Wrover-Kit is built around the ESP32, compatible with multiple modules. This kit provides several functions on a single board. The ESP32 is low cost and low power on-chip microcontroller with features such as Bluetooth and Wi-Fi. The ESP-Wrover-Kit allows users to debug the ESP32 module and build a connection between the JTAG and ESP32 via a multi-protocol USB interface. A single kit utilizes connections between the different modules such as a camera, SD card, LCD, I/O expansion connectors and, LED. What are the features of the upgraded ESP-Wrover-KIT? The Esp-Wrover-Kit-VB is the latest version of the ESP-Wrover kits launched by Espressif.

The current version is considered an ultra-low-power board. There is an 8 Mbytes expansion of PSRAM. Moreover, the onboard Micro-SD card interface is also considered as one of the major advanced features due to its high speed. Input and output expansion capabilities are also enhanced in the latest version making the overall product more versatile, fast, and smart. Why ESP-Wrover-Kit is required? Such development boards are required to make convenient secondary development and are hugely cost-effective. Researchers usually need a prototype to test their algorithms and smart applications. For example for a smart pollution measurement system requirement would be; high computation speed, ESP32, and a display unit. ESP-Wrover-Kit-VB can fulfill the requirements on a single board this is due to its camera feature.  Some other applications that require ESP32 modules and Wi-Fi connectivity are: ·         Smart surveillance ·         Teat measurement systems ·         Testing Security ·         Indoor positioning systems ·         Heart rate monitoring systems ·         Position regulation ·         Image recognition In a nutshell, as the industry continues to develop further innovative research ideas, the requirement for additional testing is equally heightened.

ESP32 CAM, caméra connectée à moins de 20€

Un nouvel article à découvrir sur le blog habitat et domotique

ESP32 CAM, caméra connectée à moins de 20€ https://www.habitat-domotique.fr/2019/04/29/esp32-cam-camera-connectee-moins-20e/

Oui, vous avez bien compris, nous allons aujourd’hui parler d’une ESP32 CAM, une caméra connectée à base d’ESP32 à moins de 20 €. L’ESP32 n’est rien de moins que le grand frère de l’ESP8266, notre module WiFi domotique préférée.

Le module que nous allons voir ensemble est un des plus complets qu’il m’a été donné de voir. Il est bien sur possible de le reprogrammer pour l’adapter à ses besoins comme par exemple une intégration à notre box domotique Jeedom, mais on verra cela dans un prochain article.

ESP32 CAM de quoi parle t’on ?

L’ESP32 apporte de nombreuse améliorations par rapport à son prédécesseur, entre autres, il est muni d’un processeur double cœur, d’un SOC Wifi/Bluetooth BLE, de 36 GPIO et de bien d’autres caractéristiques supplémentaires. Bref tout cela pour dire qu’il n’y a pas photo l’ESP32 apporte un gain de performance considérable à votre projet comparé à l’ESP8266, et tout cela pour un prix toujours raisonnable de l’ordre de 6 à 9 €.

Le terme ESP32 CAM est un terme générique qui regroupe toutes les plateformes de développement qui contienne au moins un ESP32 et un module caméra. Il en existe trois principales et je vais vous parler d’une d’entre elle en particulier en provenance du fabricant TTGO. La TTGO ESP32 CAM est munie en plus de l’ESP32 et d’une caméra OV2640 (2MP), d’un détecteur de mouvement infrarouge, d’un microphone et d’un écran OLED.

Prise en main

Comme je le disais plus haut, La TTGO ESP32 CAM nous arrive déjà paramétré avec le firmware qui va bien. Il ne nous reste qu’a le brancher à notre chargeur de téléphone pour commencer à l’utiliser.

Par défaut, il créé un point d’accès wifi sur lequel nous nous connectons avec notre ordinateur ou smartphone. Puis on se rend sur la console web d’administration. On retrouve tous les paramètres de configuration de la caméra, ainsi d’un bouton nous permettant de prendre des captures photo ou de lancer un streaming vidéo.

Il est même possible de faire de la reconnaissance faciale avec la fonctionnalité “Enroll face”, mais attention cela consomme beaucoup de ressources.

Si vous souhaitez modifier le firmware pour l’adapter à vos besoins, vous retrouverez tout le nécessaire sur le Github du constructeur. Pour mes besoins, j’ai par exemple désactivé l’affichage sur l’écran OLED et ajouté l’appel à l’API HTTP de Jeedom quand le détecteur de mouvement est déclenché afin de créer une mini camera de sécurité connectée.

Conclusion sur notre TTGO ESP32 CAM

Pour moins de 20 €, c’est un très bon produit, facile à utiliser, mais surtout adaptatif. Rien qu’avec le firmware de base, on peut faire déjà beaucoup de chose mais avec un peut de travail on peut aller très loin. Et c’est sans parler de la possibilité de lui ajouter des modules complémentaires avec l’extension 5 broches disponibles à l’arrière.

La qualité de l’image est correcte et fluide (17fps), il ne faut pas oublier que c’est un modeste 2MP. J’apprécie particulièrement la version avec le fisheye qui permet d’avoir un angle de vue relativement large. Et si vous souhaitez agrémenter le tout d’un boîtier, il existe de très beau modèles disponible sur Thingiverse.

Bref, c’est une bonne petite carte comme on les aime, on se retrouve très vite pour un nouvel article sur ce produit.
