Teracom TSH202V4 - Wire Humidity and Temperature Sensor
TSH202v3 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.
Features:
• 3.0% relative humidity accuracy
• 12-bit resolution for humidity measurements
• 14-bit resolution for temperature measurements
• Fully calibrated digital output
• Excellent long-term stability
• A unique 64-bit serial number for multi-sensor systems
Applications:
• Server room and data centers monitoring
• Humidity and temperature monitoring in building management systems
• Environmental quality monitoring and assessment
• Humidity and temperature monitoring for mobile operator facilities, vineyards, greenhouses, etc.
The sensor can be used with:
• Ethernet IO module TCW241
• Ethernet data logger TCW220
• Remote IO module TCW122B-CM
• GSM-GPRS remote monitoring controller TCG120
• IP watchdog monitoring module TCW122B-WD
• Remote environmental monitoring module TCW112-CM
• IP watchdog relay board TCW112-WD

* 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.
** Higher drift values might occur due to contaminant environments with vaporized solvents, out-gassing tapes, adhesives, packaging materials, etc.
