The two large exposed pads act as probes — functioning as a variable resistor where higher moisture means better conductivity, lower resistance, and a higher signal output. This version includes a 3-pin screw terminal pre-soldered for easy wiring.\n\nConnect VCC and GND to any Arduino-compatible board and read the analogue SIG output to determine moisture level. The PCB features a gold ENIG finish for improved corrosion resistance in moist environments.\n\nKey Features\n\n\nAnalogue Output – Signal level proportional to soil moisture content\n\nScrew Terminals – 3-pin terminal block pre-soldered for tool-free wiring\n\nENIG Gold Finish – Electroless Nickel Immersion Gold for corrosion resistance\n\nSimple Interface – Just VCC, GND, and SIG — works with any analogue input\n\n\nIdeal For\n\nAutomated plant watering systems\nGarden and greenhouse monitoring\nSoil science experiments\nEnvironmental data logging\n\n\nResources\n\n\nHookup Guide – Assembly, weatherproofing, and example project\n","vendor":"SparkFun","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":11595,"title":"Default Title","sku":"SF-SEN-13637","price":15.6,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":474,"option1":"Default Title"}]}
