OE265-11 and -14 RH Sensors
OE265-11 & OE265-14 Relative Humidity Sensor Test-
ing Instructions
Use the voltage column to check the Humidity Sensor while connected
to a powered expansion module. Read voltage with meter set on DC
volts.
Place the “-” (minus) lead on the terminal labeled GND and the “+”
lead on the AIN terminal that the Humidity sensor is connected to on
the Analog Input/Output Expansion Module.
