(3/6)
CHS-SS TYPE
For consumer and office equipment
FEATURES
• Humidity sensing characteristics exhibit virtually no hysteresis.
• Compact size.
• Low current consumption.
• Outputs DC.1V at 100(%)RH; relative humidity can be read
directly with a voltmeter.
• All-in-one construction integrates sensor with support circuitry.
The entire module operates off a 5V power supply.
• Generated ripple at low humidity levels will not exceed 2.5mV.
