is a software designed to run on a Raspberry Pi.

The software collects readings from various wired sensors, and visualizes them. Currently supported sensors include temperature, humidty, air pressure and electricity consumption. Others can be added if required.

Additionally the system supports what we call “satellite sensors”. These are single sensors wired to an ESP32 board. The board sends the readings to the main datalogger via a WLAN connection.

Satellite sensors are a good choice for larger setups where many sensors are spread over a larger area where wiring is unpractical and wifi is available.
