Overview

High performance, digital or analog HTU31 humidity and temperature combination sensor.
HTU31 humidity and temperature combination sensor

HTU31 is one of the smallest and most accurate humidity sensors on the market. Our precision engineering and 20+ years of experience in humidity and temperature combination sensors, enables us to provide fast response time, precision measurement, low hysteresis and sustained performance even when exposed to extreme temperature (-40° to 125°C) and humidity environments (0%-100%).

The HTU31 humidity sensor includes both digital (D) and analog (V) versions, and combines multiple functions and various interfaces (I2C, analog, voltage output) with an application-friendly operating voltage range (3.3-5.5V with 5V typical) and a small footprint of 2.5 x 2.5 x 0.9mm. The HTU31 humidity and temperature sensor is available in small and large volumes to meet the ever-changing demands of our customers.
