The Kitronik Mini Prong Soil Moisture Sensor is a compact sensor designed specifically for use with the BBC micro:bit. It measures soil moisture levels by using two conductive tines placed into the soil, producing an analogue voltage readable by the micro:bit.This mini version of the original Prong sensor is perfectly adapted for use with the Kitronik Greenhouse Kit for BBC micro:bit. The sensor connects to the micro:bit via crocodile clips and is powered by the 3V supply of the micro:bit.Compatible with both BBC micro:bit V1 & V2, it can be programmed using any micro:bit coding editor, including Microsoft's MakeCode editor.Features: Measures soil moisture levels accurately. Connects to the micro:bit using crocodile clips. Compatible with BBC micro:bit V1 and V2. Program with any micro:bit coding editor. Powered by the micro:bit's 3V supply. Contents:1 x Prong Soil Moisture Sensor for micro:bit.Dimensions: Length: 33mm Height: 43mm PCB Thickness: 1.6mm Requires:1 x BBC micro:bit or BBC micro:bit V2Note: For sensor longevity, avoid continuous moisture checks. It is recommended to perform moisture checks intermittently to prevent rapid erosion of the electrodes.
