The Mini Prong soil moisture sensor for micro:bit is a sensor board that can be connected to a BBC micro:bit with crocodile clips to monitor the moisture present in the 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 BBC micro:bit.
Mini Prong 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 to work with croc-clips, to connect between the Mini Prong and the micro:bit.
When fitted to the Mini Prong 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 mini 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.
Features:
- Measure soil moisture levels.
- Attaches to the micro:bit with crocodile clips.
- Code with any microbit coding editor.
- Compatible with micro:bit V1 & V2.
(Micro:bit not included).
