Corona Protected Arduino-based Touchless Doorbell

Continuously touching the bell switch by different people is harmful as coronavirus communicates via touching anything that already comes in touch with the infected person. So protection from coronavirus at the entrance (doorbell switch) is necessary.

So here in our proposed project, we designed and implemented an Automatic touchless Doorbell with the help of Arduino and MQ3 Sensor.

When someone wants to ring the bell, he/she should put his/her hands in front of the MQ3 sensor after sanitizing hands (2 to 5 cm. distance).

A Step-by-step guide with the complete circuit, code and working explanation of the Arduino Automatic Touchless Doorbell is available at electronicsforu.com

In daily aspects of our life safety and security are the two major concerns. Nowadays the scenario that we come across in many cases of human deaths and severe injuries to people is because of two wheeler road accidents. For every four minutes there is one death being reported in India. According to the World Health Organization, we have identified that 40 percent of the deaths and 70 percent of severe injuries can be reduced if bike rider wears the helmet. There are areas around the world where the traffic of people is less. In such a situation, rider’s loss their lives. On considering these factors, no proper methodologies have been implemented to avoid accidents that are caused due to alcohol consumption and unconscious riding. The helmet includes sensors which ensure if the one who is driving the two wheeler is a sober and also checks if the rider is conscious or not. With the help of alcohol sensor MQ3, we check the alcohol consumption. If detected details of the vehicle is send which includes the vehicle registration number and rider details is send to the authorizes officials. For this a database is implemented. After sleep detection using heart rate sensor, if found to be unconscious the rider is alerted with a beep sound. Thus this helmet not only ensures safe riding but also recognizes the condition of a rider for safe riding.

General Atomics MQ-1 Predator

Introducción

El primer dron en usarse profusamente en operaciones militares y civiles. Fue un proyecto ansiado tanto por el ejército norteamericano como por la CIA. Desde mediados de los 90 lleva actuando este dron en los más diversos escenarios bélicos. Dando tan buen resultado que ha sido evolucionado y copiado y servido de inspiración para muchos otros drones.

Denominado de tipo MALE (Medium Altitude Long Endurance) es el referente en esta primera etapa de uso de drones. Aunque el futuro cercano es de sus evoluciones.

Diseño

Tiene un diseño estilizado muy característico y que ha sido llevado a sus evoluciones y otros drones se han basado en él.

Fuselaje

El fuselaje es estilizado con un cuerpo muy fino. Con una hélice en la parte posterior junto al motor. Y los sensores en la parte delantera más abombada.

Tiene alas finas y gran envergadura y dos alerones en la cola en forma de bigotes. Sus dimensiones son las siguientes: longitud 8.22 metros, envergadura 14.8 metros y altura 2.1 metros.

Motor

El motor en el Predator va situado en la parte trasera del dron. Moviendo una hélice posterior que impulsa la aeronave. Es un motor Rotax de 4 cilindros opuestos turboalimentado que puede desarrollar 115 caballos a 5800 revoluciones.

Armamento

Las primeras versiones del Predator no contaban con armamento ya que se dedicaban solo a misiones de reconocimiento pero posteriormente fueron armadas con dos misiles AGM-114 Hellfire aire-suelo. También puede llevar 4 AIM-92 Stinger o 6 AGM-176 Griffin.

Sensores

El Predator lleva sensores ópticos de vídeo, una cámara de tv, que suele ser usada por el piloto. Otra cámara de tv de apertura variable para condiciones de poca luz. También montan una cámara termográfica, así como sensores de infrarrojos. Los primeros predator llevaban radar de apertura variable pero fue sustituido en versiones posteriores por su alto peso.

También puede contar con un designador de objetivos láser y medidor de distancia láser para ser usado por él mismo u otras aeronaves.

Puesto de Control

Aunque el Predador no va tripulado necesita un equipo de tres personas para ser efectivo; piloto, operador de sensores y analista de inteligencia.

El puesto de control terrestre está diseñado para ser transportado en avión, consta de 6 módulos.

Usa una conexión por satélite en banda K.

Prestaciones

A velocidad de crucero va a 5500 revoluciones por minuto desarrollando una velocidad entre 130 y 165 kilómetros por hora, pudiendo llegar a una velocidad máxima de 217 kilómetros por hora.

Tiene una autonomía de 1200 kilómetros o 24 horas de vuelo.

Puede llevar una carga de 1020 kilos.

La altura máxima a la que puede volar son 25000 pies, aproximadamente 7620 metros.

Despliegue

El sistema del Predator consta de un puesto de control, una conexión vía satélite y cuatro aeronaves. La conexión vía satélite requiere de una antena de 6 metros de diámetro.Además es necesario un equipo compuesto de 55 personas.

Historia

Desarrollo

A principios de los 80 la CIA y el pentágono estaban buscando un aparato remotamente pilotado que sirviese para misiones de reconocimiento. La CIA estaba interesada en pequeños aparatos mientras que USAF los quería de mayor tamaño.

A principios de los 90, la CIA estaba interesada en el “Amber”, un dron desarrollado por Leading Systems pero la empresa cayó en bancarrota. Fueron comprados por la CIA cinco drones y se le dio al propietario de la empresa anterior que construyera un motor silencioso. Fue conocido como Predator en ese momento.

General Atomics ganó el contrato para producir el Predator en 1994. Hasta 1996 estuvo en fase de desarrollo y pruebas, aunque participó en conflictos bélicos en este espacio de tiempo.

En junio del año 2000 empezó a converger el programa Big Safari en el programa Predator y así comenzó el proceso de armado del Predator. Al principio fueron misiles Hellfire antitanque y posteriormente otro tipo de misiles.

Misiones

El Predator se ha empleado tanto en misiones de reconocimiento con misiones de ataque aire-suelo, además de uso militar también se emplea con éxito en misiones de extinciones de incendios para ver cómo se desarrolla dicho incendio.

Se comenzó a usar en 1995 y ha participado en conflictos bélicos como Balcanes, Afganistán, Yemen, Iraq, Libia, Siria y Somalia, además de estar desplegado en distintos puntos del planeta.

En 2018 la fuerza aérea de estados unidos ha comenzado a retirarlos, sustituidos por otros drones similares pero de mayores prestaciones.

Operadores

El principal operador del Predator es Estados Unidos, y otros países también lo usan. Estos países son:

Italia

Reino Unido

Marruecos

Emiratos Árabes

Turquía

Descendientes

Este dron se ha empleado profusamente y ha sido un éxito. Muchos drones se han desarrollado basándose en el Predator tanto por parte de su fabricante General Atomics como otros estadounidenses así como por otros países.

Los principales descendientes son:

General Atomics MQ3-Grey Eagle. Parecido al Predator.

General Atomics MQ9-Reaper. Similar el Predator pero de mayor tamaño.

General Atomics Avenger. Similar al predator pero al que se le ha cambiado el motor por uno a reacción y presenta algunas características sigilosas.
