Capacitive Soil Moisture Sensor

Soil Moisture Sensor – Analog & Digital Output

This durable yet compact soil moisture sensor is perfect for monitoring moisture levels in your garden, greenhouse, or indoor plant setup. It detects the water content in soil and provides both analog and digital output signals, making it compatible with microcontrollers like Arduino, ESP32, and Raspberry Pi. With its built-in comparator, you can easily set a threshold to trigger actions like turning on a pump or activating a notification. The included power and signal indicator LEDs provide clear visual feedback, and its corrosion-resistant probes ensure reliable operation even after repeated use in moist conditions.
