The easiest way to connect the sensor is to use a 3002 - Phidget Cable 60cm or a 3004 - Phidget Cable 350cm ; cut the Phidget cable to the desired length and solder the load cell wires to the Phidget cable as follows:

3130 - Sensor Phidget Cable Function
Blue Red Supply Voltage
White Black Ground
Yellow White Humidity Output Voltage

Then, connect the load cell to any device with an Analog Input.



The Formula to translate SensorValue into Relative Humidity is:

RH (%) = (SensorValue * 0.1906) - 40.2
