I2C-TRH320-P180

Product Description

I2C-TRH320: Precision temperature and humidity probe with dual dust filter and I2C protocol.

The I2C-TRH320 is a specifically designed probe for temperature and humidity acquisition, in harsh and extreme humidity conditions. With its factory calibrated, linearized and temperature compensated sensor chip, it is field interchangeable. Thanks to its precision electronics, extremely small variations in temperature and humidity can be acquired.

The sensor communicates using a standard I2C protocol, easing integration with a wide variety of micro-controllers and single-board computers such as the Raspberry pi, Arduino and compatibles.

The compact probe eases integration, even in space-constrained locations, and the built-in particle filter provides protection against dust, soot and other contaminants.
