Features:

CATEGORY	SPECIFICATIONS
Name	Soil moisture sensor
Size	36 × 15 × 7 mm
Voltage	DC 3.3–12 V
Current	< 20 mA; < 30 mA (output)
Interface	+, -, DO, AO (DO = digital output, AO = analog output)
Operating temperature	-25 °C to +85 °C
Application	Soil moisture detection using voltage comparator; output goes low when moisture exceeds set threshold
Working principle	Measures soil moisture level and compares it with a set threshold using a voltage comparator circuit
Power connection	“+” connects to positive power and “−” to ground; reverse connection may damage the chip
Indicator function	Power indicator “P” lights up when correctly powered
Sensitivity adjustment	Blue potentiometer adjusts detection threshold; clockwise increases sensitivity threshold behavior, counterclockwise decreases it
DO output behavior	Digital output becomes low level when moisture threshold is reached; used for triggering external loads
AO output behavior	Analog voltage output readable via MCU ADC input for continuous moisture measurement
Output control notes	DO output depends on potentiometer threshold setting; AO output is independent of threshold adjustment
Circuit notes	Includes current limiting resistor (1K) and adjustable resistor (10K) for sensitivity tuning
Usage notes	Proper calibration required; incorrect potentiometer adjustment may prevent normal operation
Applications	Soil moisture monitoring, automatic irrigation systems, smart agriculture, plant watering control systems
