TSH230_R1.0 – June 2021
1.
Short description
TSH230 is a waterproof temperature and humidity sensor with 1-Wire interface.
The sensor integrates basic elements plus signal 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 bandgap element. Both elements are seamlessly coupled to a 12-bit
analog to digital converter. This results in superior signal quality.
The digital sensor is mounted in an IP65-rated enclosure with a sintered filter. This provides
protection against dust and water jets. A cable gland with locknut and screwless terminal block
allows easy cable installation.
