CAPACITIVE SOIL SENSOR

A capacitive soil sensor measures soil moisture levels without direct electrical contact, preventing corrosion. It operates by detecting changes in the dielectric constant of the soil. Unlike traditional resistive sensors, it provides more accurate and stable readings. The sensor outputs analog signals, making it compatible with microcontrollers like Arduino and Raspberry Pi. It is widely used in automated irrigation, smart farming, and greenhouse monitoring. The sensor has low power consumption, making it ideal for battery-operated applications. It is waterproof and durable for outdoor use. By monitoring moisture levels, it helps prevent over-irrigation and optimizes water usage. The non-corrosive design extends its lifespan compared to resistive alternatives. It works efficiently in various soil types and environmental conditions. The sensor is essential for IoT-based agriculture and smart watering systems.
