Lenses for social distancing
What is your project?
At present humanity is knocked down by virus called COVID19, to avoid its contagion the World Health Organization among multiple precautions recommends a social distancing of at least 1 meter (3 feet) of distance between you and other people [1]. As an alternative to help solve this problem, develop lenses with a distance ultrasound sensor, with an indicator (LED) that gives a visual alert to get away from people.
Why did you decide to do it?
From my point of view this is a contribution to study and validation of the recommendations that WHO tells us to avoid the spread of COVID-19, additionally it trains us with a light alert a social approach in times of pandemic.
How does it work?
The lens has an HC-SR04 [2] ultrasonic sensor specially designed for distance measurement, among many alternatives it was chosen for its low price and low power consumption, all controlled by the Atmega 328p microcontroller and programmed with the Arduino IDE, the idea is a very economic development and easy to build since communities can adapt the majority of current lenses to the detection and alert system.
The system has an integrated battery charge sensor that can optionally include the code to emit a low battery alert.
To develop a robust code that performs 2 measurements and a comparison with the previous measurement (to avoid false alarms) before making an alert decision and thus make the decision to activate or not the light alert.
Thank you very much for the opportunity, if you want to help me financially to develop the next improved version I would really appreciate it.

?Cuál es su proyecto?
En la actualidad la humanidad esta abatida por virus llamado COVID19, para evitar su contagio la Organización Mundial de la Salud entre múltiples precauciones recomienda un distanciamiento social de al menos 1 metro (3 pies) de distancia entre usted y las demás personas [1]. Como una alternativa para ayudar a resolver este problema desarrolle unos lentes con un sensor de ultrasonido de distancia, con un indicador (LED) que da una alerta visual para alejarse de la personas.
?Por qué decidió hacerlo?
Desde mi punto de vita esta es un contribución para estudio y validación de las recomendaciones que OMS nos dice para evitar el contagio del COVID-19, adicionalmente nos entrena con una alerta lumínica un acercamiento social en tiempos de pandemia.
?Cómo funciona?
El lente tiene un sensor ultrasónico HC-SR04 [2] especialmente dise?ado para la medición de distancia, entre múltiples alternativas se escogió por su bajo precio y bajo consumo eléctrico, todo controlado por el microcontrolador Atmega 328p y programado con el IDE de Arduino, la idea es un desarrollo muy económico y fácil de construir ya que las comunidades pueden adaptar la mayorías de lentes actuales al sistema de detección y alerta.
El sistema tiene integrado un sensor de carga de batería que opcionalmente se puede incluir el código para emitir un alerte de baja batería.
Para desarrollo un código robusto que realiza antes de tomar una decisión de alerta 2 mediciones y una comparación con la medida anterior (para evitar falsas alarmas) y así tomar la decisión de activar o no la alerta lumínica.
Muchas gracias por la oportunidad, si desean ayudarme económicamente para desarrollar la siguiente versión mejorada mucho se lo agradecería.
