Description

The Soil Humidity Sensor Module (Hygrometer Sensor) is a simple yet effective device for detecting the moisture level of soil , ideal for Arduino-based automatic watering and smart garden projects . It works by measuring the electrical resistance between two probes inserted into the soil — the wetter the soil, the lower the resistance. The sensor outputs both analog and digital signals , allowing precise moisture monitoring and easy triggering of relays or pumps in automated irrigation systems . This module is ideal for DIY projects, greenhouse automation, and environmental monitoring , providing an easy way to maintain healthy plant growth with minimal effort.

Key Features

Dual output (analog + digital) for flexible control and monitoring.
Simple plug-and-play connection for microcontrollers.
Adjustable sensitivity for different soil types.
Helps automate irrigation systems efficiently.
Cost-effective and reliable solution for small and large-scale plant monitoring.
