Pin
Description
+
Power supply 5V/DC
-
Ground
S
Analog Output pin
Description:
This Soil Moisture Sensor is a simple breakout for measuring the moisture in soil and
similar materials. The two large exposed pads function as probes for the sensor,
together acting as a variable resistor. The more water that is in the soil means the
better the conductivity between the pads will be and will result in a lower resistance,
and a higher SIG out.
Specification
Power Supply: 3.3V or 5V
Working Current: Less than 20mA
Output Voltage: 0~3.0V when 5V power supply; 0~1.7V when 3.3V power
supply
Sensor Type: Analog output
Service Life: 1 year approximately
