Sensirion SHT3x - Digital Humidity & Temperature Sensors (RH/T)

Sensirion is the leading manufacturer of high-quality sensors and sensor solutions for the measurement and control of humidity, and of gas and liquid flows. 

Following on from the industry leading SHT2x series Sensirion has released the new humidity and temperature sensor series SHT3x and in doing so is taking sensor technology to a new level. The SHT3x series contains a low cost version with the SHT30, a standard version with the SHT31 and a high end version (with the SHT35, available Q4/2015). The SHT3x series thus combines multiple functions and various interfaces (I2C, voltage out) with a user-friendly, very wide operating voltage range (2.4 to 5.5 V). These sensors are suitable for large volumes as well as for low volumes.

SHT30 - low cost version, +/-3% RH accuracy
SHT31 - standard version, +/-2% RH accuracy
SHT35 - available Q4 2015


  • Size: 2.5 x 2.5 x 0.9 mm
  • Output: I²C, Voltage Out
  • Supply voltage range: 2.4 to 5.5 V
  • Energy consumption: 4.8µW (low repeatability, 1 Measurement / s)
  • RH operating range: 0 - 100% RH
  • T operating range: -40 to +125°C (-40 to +257°F)
  • RH response time: 8 sec (tau63%)

Why choose Sensirion? 

RH accuracy over a wide  range simply can't be beaten. Furthermore the accuracy of performance between different sensors is replicable compared to others which show wide variation. Comparison graphs showing true performance compared to data sheet performance are available upon request. Speak to us today to understand the many other reasons as to why Sensirion sensors are the gold standard compared to the rest.
