Pro Humidity Sensor for Automotive Applications

Sensirion’s SHT3xA sensor is today’s industry standard for humidity and temperature sensing in automotive applications. Its design and reliability is specifically optimized to meet the high quality standards of the automotive industry.

SHT3xA integrates CMOSens® sensor chip and all required electronics for signal processing from sensor into easy to use electronic component that offers high accuracy and robustness at the lowest power consumption and a very compact size.

Integration into electronic systems requires minimum effort thanks to factory calibration, I2C interface, wide supply voltage range 2.4 to 5.5 V and standard reflow solderability.

Sensirion also offers STS3xA temperature sensor for applications where only temperature measurement is required.

Common Features of both SHT3xA and STS3xA sensors:
  • Advanced automotive grade sensor (AEC-Q100)
  • Size: 2.5 mm x 2.5 mm x 0.9 mm 
  • Interface: I2C with two selectable addresses
  • Supply voltage range: 2.4 V to 5.5 V
  • Different accuracy grades available (SHT30A, SHT31A, STH35A)
  • Programmable alert function
  • Low current consumption: 1.7 µA
  • Ambient temperature operating range: -40°C to 125°C (-40°F to 257°F)
SHT3xA:
  • RH operating range: 0 to 100% RH
  • RH response time: 8 sec (τ63%)
Applications:
  • Climate control
  • Anti-fogging
  • RH/T condition monitoring for climatic management of critical electronics
Core values to automotive market:
  • Meets quality requirements of the automotive industry according to IATF 16949 and AEC-Q100
  • High reliability, robustness and accuracy
  • More than 20 years of experience in the field of humidity and temperature sensing
  • Proven track record: third generation of humidity sensors in the automotive sector
Evaluation Kit

Sensirion currently offers only standard versions SHT31-DIS-B and SHT35-DIS-B on flex PCB, SHT30 and STS3x on flex PCB are not available at the moment. The easiest way to get started with SHT3x humidity sensors is using SEK SensorBridge, SEK-SHT31-Sensors or SEK-SHT35-Sensors and viewer software ControlCenter.

We will be happy to provide you with samples of the SHT31A-DIS-B and STS30A-DIS sensors for testing. Please, contact your sales representative.
