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.
