Teracom 1-Wire humidity and temperature sensor TSH202v3

Model TSH202v3

Short Description

The TSH202v2 provides a low-cost option for humidity and temperature monitoring. The sensor communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multiple sensors to be connected on the same 1-Wire bus.

The TSH202v2 integrates basic elements plus signal processing and provides a fully calibrated digital output.

A unique capacitive element is used for the humidity sensor. 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

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-WDv
* Remote environmental monitoring module TCW112-CM
* IP watchdog relay board TCW112-WD

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

Technical Parameters

Operating Range: 10 to 90%RH non condensing -20 to +60°C
* 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.
