General description
Today’s demand for energy efficient sensors in appliance, consumer, industrial,
and medical applications require optimal system performance to meet
environmental and end user expectations.
The 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). The HTU31 humidity and temperature sensor is available in small and
large volumes to meet the ever-changing demands of our customers.
