TSH202v3 1-Wire humidity and temperature sensorShort description 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. • 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. Parameter Value Units Remark Value Units Remark Operating Range 10 to 90* %RH non-condensing -20 to +60* °C Cable length 1 meter * 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. www.teracomsystems.com

TERACOM TSH202v3 - 1-Wire humidity sensorUsage Can be used with following TERACOM controllers - TCW241 - TCW122B-CM - TCW122B-WD - TCW112-WD Pinout Signals VDD (+4.0 to +5.5V) Data GND (Ground) Cable colors Yellow Red Green White Brown Black Status indicator The status of the device is shown by single LED, located on the front panel: • If the LED blinks on period of 1 second, sensors works properly; • If the LED blinks on period of 3 seconds, there isn't communication with TCWxxx controller; • If LED doesn't blink, there isn't power supply.
