Description
This soil hygrometer sensor module is ideal for detecting moisture levels in soil, perfect for smart garden projects and environmental monitoring.
It’s designed to interface easily with microcontrollers such as Arduino, Raspberry Pi, and ARM-based systems.
Using the two exposed pads as probes, the sensor acts as a variable resistor more moisture results in lower resistance and higher output voltage.
