Product Specifications Product Name Soil Moisture SensorSize 36 15 7mmVoltage 3 3 12VDCCurrent Working 20mAOutput 30mAInterface DO digital AO analogWire Length 1 2mNotice 1 is connected to the positive pole of the power supply is connected to the negative pole of the power supply Please do not reverse the connection It is responsible for burning the chip After the power is connected the P power indicator lights up and the module works normally 2 The blue potentiometer adjusts clockwise counterclockwise to increase decrease the probe detection sensitivity Take the thermal sensor as an example assuming the default is 25 degree trigger DO output is active low Clockwise adjustment the temperature can be triggered below 25 degrees Counterclockwise is higher than 25 degrees trigger 3 It indicates that the adjustment range has exceeded the test threshold when the potentiometer is adjusted clockwise until the S output indicator is on The threshold value is exceeded when the counterclockwise adjustment is unable to adjust The threshold cannot be exceeded when adjusting otherwise it cannot be used 4 AO output is analog voltage which can be directly detected by the AD port of the MCU Package Include 1 Soil Moisture Sensor
