Soil Moisture, Humidity Sensor Module

Description

The soil moisture sensor functions by measuring electrical conductivity between its metal probes, offering essential data on soil moisture levels crucial for efficient irrigation and environmental monitoring. Ensuring accurate readings and reliable functionality requires regular calibration and maintenance.

The Soil Moisture Meter is thoughtfully designed, featuring a dual output mode that prioritizes precise analog output. Additionally, it includes a fixed bolt-hole for easy installation, a power indicator (red), and a digital switching output indicator (green). Stability is guaranteed through the LM393 comparator chip, operating effectively within a voltage range of 3.3V to 5V. This sensor employs two probes to gauge soil moisture, where increased moisture levels result in decreased resistance, signaling the need for watering

This digital soil moisture sensor is user-friendly, providing a digital output of 5V for high moisture levels and 0V for low levels in the soil. With an adjustable potentiometer, users can set their desired moisture threshold. Versatile in application, this sensor finds utility in water gardening projects, water sensing, and more.
