This is a small system that reads a few sensors (described below) and send its raw data via MQTT.
The original intention is to integrate it into Home Assistant so that via some high level logic on Home Assistant a pump can be activated.
- Arduino Uno R4 WiFi
- 1x TDS Sensor (CQRSENTDS01)
- 1x pH Sensor
- 2x Discrete water level sensors (float sensors) (I have these)
These are configurable in conf.h.

o D3 -+- Water high sensor

Enter your WiFi SSID/password as well as the MQTT broker IP address, port and credentials in the conf.h file.
