Humidity Sensor Units

CHS Series CHS-U, -SS, -C Types

TDK’s CHS series humidity sensors are compact and extremely

simple to apply. Because they contain the necessary circuitry,

there is no need to provide additional control circuitry or perform

time-consuming calibration. With simple connection to a power

supply, they will output DC at 100% relative humidity. This makes it

possible to read RH directly with a voltmeter.
