(5/6)
CHS-C TYPE
For consumer and office equipment
FEATURES
• Temperature detection thermistor can be added.
• Humidity sensing characteristics exhibit virtually no hysteresis.
• Low current consumption.
• Absolute humidity can be read directly with DC. 1V voltmeter.
• All-in-one construction incorporates circuits and 5V power
supply operation.
• Generated ripple at low humidity levels will not exceed 2.5mV.
