The Gravity: Analog Soil Moisture Sensor (SEN0114) is a reliable and easy-to-use sensor designed to measure the moisture level in soil. Ideal for smart gardening, urban agriculture, and plant care projects, this sensor helps you monitor when your plants need watering-perfect for IoT garden systems or agriculture automation.
This module uses two probes to measure the soil's electrical resistance: the wetter the soil, the lower the resistance. It's a simple, effective way to detect moisture changes and trigger automated responses.
Built with a corrosion-resistant design and equipped with a Gravity 3-pin interface, the sensor supports plug-and-play operation with Arduino and other microcontrollers-no soldering or wiring hassle.
