The soil moisture sensor for micro:bit is a sensor board that can be directly mounted to a micro:bit to monitor the moisture present in soil. The two conductive tines are placed into the soil. Any water or moisture in the soil will conduct to give an analogue voltage that can be read by the micro:bit.

The sensor is powered from the 3V supply of the micro:bit. Use either the USB or JST connector on the micro:bit to power the circuit.

The board has been designed so that the micro:bit can be bolted on using 3 x M3 nuts and 3 x M3 screws. Place the screws through the P1, 3V and GND holes of the PCB and micro:bit, then use the M3 nuts to fasten together on the back of micro:bit. Alternatively croc-clips can be used to connect between the sensor and the micro:bit.

When fitted to the moisture sensor, the micro:bit can be coded via any of the micro:bit editors, such as the Microsoft MakeCode editor.

Note: To ensure that the Prong moisture sensor has a long and fulfilling life, it is better to write your code to perform a moisture check every so often rather than continuously. When the check is performed continuously it promotes rapid erosion of the electrodes.

Measure soil moisture levels.
- Attaches directly to the microbit.
- Code with any microbit coding editor.
