Description :

• SparkFun Soil Moisture Sensor is a simple breakout board for measuring soil moisture
• The two large pads act as probes, functioning as a variable resistor
• The more water in soil, the lower the resistance and higher SIG out
• VCC and GND pins connect to an Arduino-based device
• SIG out depends on the amount of water in soil
• PCB coated in gold finishing (ENIG) for longer lifespan when exposed to a moist environment
• Includes 3-pin screw pin terminal pre-soldered for easy wiring and setup
