Capacitive Soil Moisture Sensor V1.2

is an upgraded and highly durable soil moisture sensing module designed for precision irrigation, agriculture automation, and smart gardening. Unlike traditional resistive probes that corrode easily, uses capacitive sensing technology to measure soil moisture without direct exposure of metal parts to the soil. This ensures long-lasting performance, stable readings, and superior resistance to oxidation.

This sensor is widely used in smart farming systems, home plant monitoring, greenhouse automation, hydroponics, and educational STEM projects. It delivers real-time analog output that changes based on soil moisture levels, allowing microcontrollers like Arduino, Raspberry Pi, ESP32, and NodeMCU to continuously monitor soil conditions and trigger irrigation systems automatically.
