Ultra-high accuracy humidity and temperature sensor.

The highest accuracy for humidity and temperature backed by many years of sensing technology expertise.

Sensirion's new high-precision SHT45 humidity sensor offers an good value for its price on the market and extends the use of high-performance applications. Tape and reel packaging, combined with its suitability for standard SMD assembly processes, make the SHT45 ideal for high-volume applications.

The SHT45 builds on a new and optimized CMOSens® chip, offering ultra-low power consumption and high accuracy specifications. Sensirion’s CMOSens® Technology provides a complete sensor system on a single chip thanks to a fully calibrated digital I2C fast-mode plus interface. The SHT45 covers operating ranges from 0 to 100 % RH and from -40°C to 125°C with accuracies of ± 1 % RH and ΔT = ± 0.1°C, ensuring reliable measurement results thanks to its long-term stability and high precision. With an extended supply voltage range of 1.08 V to 3.6 V and 400 nA average current, the SHT45 is perfectly suited for the most demanding applications. The small size in a robust DFN housing enables integration into challenging designs while meeting the strictest reliability demands, as demonstrated by its JEDEC JESD47 qualification.

“We are continuing to push the boundaries of humidity sensing with the SHT45 through increased accuracy and a wide supply voltage range. Thanks to more than 20 years of experience in developing humidity sensor technology and our end-of-line testing, we can guarantee the accuracy specifications for every part shipped,” says Maximilian Eichberger, Director of Humidity and Temperature Sensor Product Management at Sensirion.
