The SHT40 builds on a completely new and optimized CMOSens® chip offering ultra-low power consumption and industry-leading accuracy specifications. Sensirion’s CMOSens® Technology provides a complete sensor system on a single chip, with a fully calibrated digital I2C fast-mode plus interface. The sensor covers operating ranges from 0 to 100 % RH and from-40°C to 125°C with accuracies of ±1.8% RH and ±0.2°C. With the extended supply voltage range from 1.08 V to 3.6 V and 400 nA average current, the SHT40 is perfectly suited for mobile and battery-driven applications.
In 2021, the high-accuracy versions SHT41 and SHT45 will be available. They feature typical and maximal accuracies that have been honed down to ∆RH = ± 1.5% RH and ∆T = ± 0.1°C, making them suitable for the most demanding applications in all industries (more info).
