  • •Humidity sensors
  • •SHT3x

±2% Digital humidity and temperature sensor, ISO17025 certified

The SHT3x humidity sensor series combines multiple functions and various interfaces (I²C, analog voltage output) with an applications-friendly, very wide operating voltage range (2.15 to 5.5 V). Every single SHT33 comes with its individual ISO17025 3-point temperature calibration certificate, proving its sensing capabilities to the highest standards. The SHT33 humidity sensor is available in both large and small volumes and is perfectly suited for cold and frozen chain applications in the pharmaceutical field and is specifically designed for operations in –30 to 70 degrees.
