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.
Connections
We tested TSH202 sensor with FMB120 & FMC130 devices and connections will be as per following sequence.
| TSH202 wire color | Connections |
|---|---|
| Red | +VDD (+4.0 to +5.5V) 1-wire power of FM device |
| White | 1-wire signal of FM device |
| Black | Ground of FM device |
Configuration
- Use Firmware ver.03.27.13.Rev.480.e and above.
- Use Teltonika.Configurator_1.7.30_E.THS202_R.4 and above.
