THE-1105 | Sensor: Room Temp, Hum

The THE-1105 can be wall-mounted in vertical or horizontal installations for building automation systems requiring accurate monitoring of humidity and temperature. It transmits separate relative humidity (RH) and temperature signals for use in temperature, humidity, or enthalpy-based control applications. Environmentally rugged, it is suitable for hospitals, laboratories, and swimming pool areas.

This transmitter uses a silicon CMOS chip sensor (providing much more durable and reliable performance than older capacitive polymer sensors). It responds within seconds to changes in humidity with a very high degree of accuracy.

For humidity readings, the THE-1105 has two user-selectable output ranges: 0 to 5 or 0 to 10 VDC (scaled over 0 to 100% RH range).

The THE-1105 also contains a thermistor for measuring room temperature. The Type II 10,000 ohm (@ 77° F) thermistor provides precise, stable temperature sensing.

NOTE: For a more compact sensor, see the THE-1102. For duct-mounted applications, see the THE-1002.
