 The sensors are built from scratch with an `ESP32` as compute unit

 The software is based on `platform-io` and is therefore easy to build and deploy.
 
 The sensor data is sent via W-LAN and MQTT protocol to `home assistant` on the backend server.
 Home assistant is at first place a home automation system.
 But one part of automation is to collect data from sensors.
