DESCRIPTION
3 Sets Soil Moisture Sensor, with Probe, Module Digital2831
Working Voltage: DC 3.3-12V
Working Current: Less than 20mA (Output Current: Less than 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 outputDigital Value Output
Instructions:
1."+" connects power positive; "-" to negative. Don't connect reversely or the chip be burnt out. There is a LED power indicator at the P mark on the board. It if the module operates normally.
2.Clockwise/counter-clockwise rotate the blue potentiometer to increase/reduce the detection threshold. For example, DO outputs low level when the moisture reaches 50% now, then I clockwise rotate the potentiometer to increase the detection threshold. At this time, DO outputs a low level only when the moisture reaches a point higher than 50%.
3. If you clockwise rotate the potentiometer to an extent that the LED indicator which marked "S" is light, that means the testing threshold has been surpassed. Counterclockwise rotating to surpasses the threshold too. The module not work well if the detection threshold is invalid. NOTE: The threshold adjustment only works for using the DO output.
