Kitronik Mini Prong Soil Moisture Sensor for BBC micro:bit

The Kitronik Mini Prong Soil Moisture Sensor is a specialised, compact board designed to work seamlessly with the BBC micro:bit, enabling the monitoring of moisture levels in soil for educational and hobbyist projects. Its short tines are a specially adapted version of the original Prong sensor, making it the perfect component for use with the Kitronik Greenhouse Kit for BBC micro:bit.

This sensor board operates on a simple yet effective principle: the two conductive prongs are inserted into the soil, and any present moisture allows a current to pass between them. This creates an analogue voltage that can be read directly by the connected BBC micro:bit. The board is designed for easy connectivity using standard crocodile clips, requiring no soldering or complex wiring, which makes it ideal for beginners and classrooms.

Key Features & Compatibility

• Easy Measurement: Accurately measures soil moisture levels to inform watering schedules or automate greenhouse systems.
• Simple Connection: Attaches directly to the BBC micro:bit using crocodile clips for a quick and tool-free setup.
• Full Compatibility: Works flawlessly with both the original BBC micro:bit V1 and the newer BBC micro:bit V2.
• Flexible Programming: Write code for it using any popular micro:bit coding editor, such as MakeCode or Python, allowing for customisable projects and data logging.

With its robust design and educational focus, this sensor is an excellent tool for introducing students to concepts of environmental monitoring, basic electronics, and computational thinking.
