TeraCom TSH202

Introduction

TeraCom TSH202 is humidity and temperature sensors with a 1-Wire interface. The device integrates basic elements plus signals processing, and provides a fully calibrated digital output. A unique capacitive element is used for measuring relative humidity while the temperature is measured by a band gap sensor. Both sensors are seamlessly coupled to a 12-bit analog to digital converter. This results in superior signal quality and fast response time.

Applications

  • Server room and data centers monitoring.
  • Environmental quality monitoring and assessment.
  • Humidity and temperature monitoring in building management systems.
  • Humidity and temperature monitoring for mobile operator facilities, vineyards, greenhouses, etc.

Technical parameters

NAME DESCRIPTION
Interface 1-Wire Interface
Wiring White = 1-wire signal, Red = 1-wire power, Black = Ground
* Operating temperature -20 ºC to +60 ºC
* Operating humidity 10 to 90%RH
Tolerance typ. ±3.0 %RH (20 to 80 %RH), ±0.4 °C (-10 to +60°C)
Tolerance max. ±5.0 %RH (10 to 90) %RH, ±1.0 °C (-20 to +60°C)
Power supply/consumption 4.0 to 5.5 VDC, 5 mA
Dimensions 45 x 16 x 10
Cable length 1 m

* Recommended operating range is 20% to 80% RH (non-condensing) over -10°C to +60°C.

Prolonged operation beyond these ranges may result in a shift of sensor reading, with slow recovery time.

Installation

  • TSH202 will be connected with FM devices via 1-wire interface.
  • To connect the 1-wire TSH202 sensor you have to make sure to connect 3 PINs of the sensor to the PINs of your device correctly.
