{"title":"Prong Soil Moisture Sensor for BBC micro:bit","handle":"prong-soil-moisture-sensor-for-bbc-micro-bit","url":"/products/prong-soil-moisture-sensor-for-bbc-micro-bit","description":"The Prong Soil Moisture Sensor mounts directly onto a BBC micro:bit to monitor soil moisture levels. Two conductive tines are inserted into the soil — any moisture conducts an analogue voltage that the micro:bit reads on Pin 1, ranging from 0 V (dry) to 3 V (wet).\n\nPowered from the micro:bit's 3 V supply via USB or JST. Attach the board using the included M3 hardware through the P1, 3V, and GND holes, or connect with crocodile clips. Compatible with MakeCode, Python, and other micro:bit editors.\n\nKey Features\n\n\nDirect micro:bit Mount – Bolts onto the micro:bit with M3 hardware\n\nAnalogue Output – Reads soil moisture on Pin 1\n\n3 V Powered – Runs from the micro:bit's built-in supply\n\nMi:Power Compatible – Add a Mi:Power board for standalone operation with audible alarm on P0\n\nCrocodile Clip Option – Connect without soldering\n\n\nSpecifications\n\n\nLength – 68 mm\n\nHeight – 53 mm\n\nPCB Thickness – 1.6 mm\n\n\nIdeal For\n\nPlant watering monitors and smart garden projects\nSTEM and classroom experiments\nStandalone environmental sensing with Mi:Power board\n\n\nPackage Contents\n\n1× Prong Soil Moisture Sensor\n3× M3 hex nuts\n3× M3 countersunk screws\n\n\n\nNote: Requires a BBC micro:bit (sold separately). To prolong electrode life, take periodic moisture readings rather than continuous sampling.\n","vendor":"Kitronik","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6799,"title":"Default Title","sku":"KI-5647","price":6.67,"on_sale":false,"in_stock":true,"available_quantity":101,"option1":"Default Title"}]}
