What's you project about? My project is a prototype of a disinfection cabin, since now with the pandemic it is very important to take care of ourselves, so a disinfection cabin is very important in almost all public places, such as companies, restaurants, schools and even in homes, to prevent the spread of COVID-19

Why did you decide to do it? It is very important to take care of ourselves so as not to get sick, so we must follow the health regulations and take care of ourselves as well as sanitize all and in turn disinfect ourselves at all times.

How does it work? It works thanks to the Arduino nano, it is the brain of this project that, based on the HC-SR04 ultrasonic sensor, upon detecting an obstacle at a certain distance, it will send a pulse to the microcontroller that you see will activate a 110 or 220 volt A.C. water bobma. For this, a relay is connected to be able to activate the pump. The system is programmed for a 10 second sanitization, it will also keep a count of how many people are using the system through the LCD screen. Use the I2C interface to simplify screen connections to only use 2 analog ports of the arduino.
