Soil Moisture Sensor with Corrosion Resistant Probe for Garden Automatic Watering System

Specifications of the Soil Moisture Sensor and Soil Detector Module: - Working Voltage: DC 3.3-12V - Working Current: <20mA (Output Current: <30mA) - Sensor Probe Length: 8.8cm/3.46 inch - Sensor Pin Pitch: 5 mm - Sensor Cable Length: 1.2 meters /3.94ft - Sensor Connecting Port: XH2.54 2P - DO Port: digital value output (DO output current is about 10mA) - AO Port: analog value output

The soil moisture sensor outputs a low level from the DO port when the detecting humidity reaches the threshold value, making it compatible with Arduino/Raspberry Pi. The AO port on the sensor outputs an analog value(voltage), allowing you to acquire real-time data via the AD port of your single-chip microcomputer(MCU).

The detection threshold can be adjusted by clockwise/counterclockwise rotation of the blue potentiometer. The on-board power and signal indicator provides the working status of the board at a glance. The instruction includes connecting power positive to "+" and power negative to "-", with a warning against reverse connections. The LED power indicator at the P mark on the board will light up if the module operates normally.

The probe uses analog resistance to detect the moisture content of the soil, serving as an ideal tool for monitoring plant hydration and for use in automatic watering systems, gardens, greenhouses, and more.
