Sensirion reveals the new high-precision SHT45 humidity sensor as part of Sensirion’s 4th-generation humidity sensors – the SHT4x series. The SHT45 offers the highest accuracy for humidity and temperature backed up by Sensirion’s many years of sensing technology expertise.

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 (more info).
