Soil Moisture Hygrometer Detection Humidity Sensor Module

Introducing the Soil Hygrometer Humidity Detection Module, an essential tool for monitoring soil moisture levels with precision. This module is designed to detect moisture in the soil, offering a high level of sensitivity to ambient humidity. Whether for home gardening or automated watering systems, this sensor ensures optimal plant care without the need for constant manual intervention.

Featuring two probes, this sensor measures the volumetric content of water in the soil. As the soil’s moisture content changes, so does its electrical conductivity. When the soil is dry, it exhibits higher resistance to electricity, resulting in a high-level output from the module. Conversely, when the soil is moist, it conducts electricity more efficiently, leading to a low-level output. This enables accurate measurement and monitoring of moisture levels, ensuring timely watering when needed.

Interface Description (4-wire):

1. VCC: 3.3V – 5V
2. GND: Ground
3. DO: Digital output interface (0 and 1)
4. AO: Analog Output Interface

The threshold value can be easily adjusted via the potentiometer. The DO port outputs a high signal when soil humidity exceeds the set threshold, while the analog output (AO) provides more precise moisture level values through the AD converter.

Features:

• Dual output mode: analog output for accuracy, digital output for simplicity
• Fixed bolt hole for easy installation
• Power indicator (red) and digital switching output indicator (green)
• Utilizes LM393 comparator chip for stability
• Operating Voltage: 3.3V – 5V

Specification:

Ensure optimal soil moisture levels for your plants with the Soil Hygrometer Humidity Detection Module, your reliable partner in gardening and plant care.
