Product Specification

General Description:

    The HTU31 is one of the smallest and most accurate humidity sensors on the market. TE Connectivity precision engineering and 20+ years of experience in humidity and temperature combination sensors, enabled this new product with fast response time, precision measurement, low hysteresis, robustness to reflow assembly process and sustained performance even when exposed to extreme temperature [-40°to125℃]and humidity [0%RH to 100%RH] environments.

    HTU31 humidity & temperature sensor includes both digital (D) and analog (V) versions and combines multiple functions with an application-friendly operating supply voltage range from 3V to 5.5V.

    HTU31 sensor is available in small and large volumes to meet the everchanging demands of our customers.
