Project Description

Short Description

TSH202 is indoor digital humidity sensor, measuring also temperature.  It provides a low cost option for humidity and temperature monitoring for home and industrial automation. 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.

TSH202 integrates basic elements plus signals processing and provide a fully calibrated digital output. A unique capacitive element is used for humidity sesnsor while 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.

TSH202 is supported by TCW1xx, TCW2xx and TCG1xx series of controllers.
