1-Wire temperature and humidity sensor TSM400-1-TH

TSM400-1-TH is a combined temperature and humidity sensor with a 1-Wire interface.


TSM400-1-TH is a digital temperature and humidity sensor with a 1-Wire interface. Its construction is designed for wall mounting, making it suitable for monitoring of server rooms, data centers, offices, stores etc.

The digital temperature and humidity sensor integrates basic elements as well as signals processing and provides a fully calibrated digital output. This results in superior measurement quality.

The sensing elements are factory calibrated and do not require any lifetime recalibration.

TSM400-1-TH communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multi-sensors support on the same 1-Wire bus.

TSH400-1-TH is housed in a slim plastic enclosure. The bottom part of the enclosure is suitable for installation on standard flush-mounted / cavity wall boxes ø68mm, with installation openings on 61 mm.

Controlling humidity is important in providing a healthy environment in the offices, workplaces, schools, and other public buildings.
