    I have some hc sr04 sensors (ultrasound sensor) installed on 4 chairs (see photo of red chairs) and each connected to an Esp8266. When a person sits on a chair the sensor detects it because the distance is less than thirty cm and a command is sent via wifi to a raspberry PI on which some videos must be started. I already have some scripts for Arduino (for each Esp8266) and a python file for the ra...
