Based on the Sensirion SHT31 and SHT-35 sensors, the I2C-TRH series is designed for OEMs who wish to integrate our sensors into their applications.
The sensor communicates using a standard I2C protocol, which facilitates integrating various compatible microcontrollers and single-board computers such as Raspberry Pi, Arduino, etc. These sensors can be used for temperature and humidity acquisition in challenging and extreme humidity conditions.
The factory-calibrated, linearized and temperature-compensated sensor chip makes it an interchangeable sensor in the field. Thanks to its precision electronics, it is possible to acquire extremely small temperature and humidity variations. Its compact probe makes it easy to fit in areas where space is at a premium, and the built-in particulate filter protects from dust, soot and other contaminants.
