The Hygrometer Soil and Moisture Sensor Module is a simple yet effective tool for monitoring the water content in soil, making it an essential component for automatic irrigation systems, smart gardens, and agriculture projects. This sensor works by detecting the resistance between its probes, which changes depending on the soil’s moisture level. The output can be used to determine whether the soil is dry, moist, or adequately watered.
The module typically provides both analog and digital outputs. The analog output allows continuous monitoring of soil moisture, while the digital output, set using an onboard potentiometer, gives a HIGH/LOW signal depending on a defined threshold. It is compatible with Arduino, ESP8266, ESP32, STM32, Raspberry Pi, and other microcontrollers, making it an excellent choice for DIY electronics and IoT-based smart farming solutions.
With this sensor, you can easily automate plant watering systems, ensuring your plants and crops receive the right amount of water. It is highly suitable for greenhouses, indoor plants, and precision agriculture.
