TSH202 is a 1-Wire humidity and temperature sensor. It 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 sensor communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows a few 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

A unique capacitive element is used for humidity sensor 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.
