Product details

With this capacitive soil moisture sensor from DFRobot, you can easily measure the moisture of plants and determine when they need to be watered. The sensor features a built-in amplifier, allowing it to be connected directly to an analog input of an Arduino. The measuring probe is inserted into the soil and measures the soil's capacitance, which changes with moisture levels. This capacitive soil moisture sensor has no wear or corrosion like a conventional soil moisture sensor, making it more durable.

Note: Since the sensor's cut edges are not sealed, moisture may enter the circuit board through the cut edge. To extend its lifespan, you should seal the cut edges with clear lacquer or epoxy resin.
