Description:
The Soil Humidity Moisture Detection Sensor Module with Probe, featuring the LM393 comparator, is designed to accurately measure soil moisture levels for various agricultural and horticultural applications. The module operates by passing current through the soil via its dual probes, measuring the resistance to determine moisture content. Higher moisture levels result in lower resistance, while drier conditions increase resistance. This sensor is ideal for automated irrigation systems, ensuring plants receive optimal watering based on real-time soil conditions.
Equipped with both digital and analog outputs, the module offers flexibility in interfacing with microcontroller platforms such as Arduino and Raspberry Pi. The digital output can be adjusted using the onboard potentiometer to set specific moisture thresholds, triggering alerts or actions when soil moisture falls below the desired level. The analog output provides a variable voltage corresponding to the exact moisture level, allowing for more nuanced monitoring and control. The module’s compact design and ease of integration make it a valuable component for both hobbyist projects and professional agricultural systems.
