Introducing the Soil Hygrometer Humidity Detection Module, a crucial tool for accurately monitoring soil moisture levels. Designed for high sensitivity to ambient humidity, this module is perfect for home gardening and automated watering systems, ensuring optimal plant care without constant manual intervention.
Equipped with two probes, the sensor measures the volumetric water content in the soil. As moisture levels change, so does the soil’s electrical conductivity. When the soil is dry, it exhibits higher electrical resistance, 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 functionality enables precise measurement and monitoring of moisture levels, ensuring timely watering when necessary.
Specifications:
Sensitivity adjustable using a potentiometer
Operating voltage: 3.3V – 5V
Dual output mode: digital output for simplicity, analog output for precise measurements
Fixed bolt hole for easy installation
Compact PCB size: 3cm * 1.6cm
Features power indicator (red) and digital switching output indicator (green)
Equipped with LM393 comparator chip for stability
Interface Description (4-wire):
VCC: 3.3V – 5V
GND: Ground
DO: Digital output interface (0 and 1)
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.
