SHT45
±1.0% RH / ±0.1°C Digital humidity and temperature sensor
In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT45 offers the best price-performance ratio on the market. 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 completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. With the extended supply voltage range from 1.08 V to 3.6 V, it’s the perfect fit for mobile and battery-driven applications. The exceptionally small size in a robust DFN housing enables integration into challenging designs while meeting the highest reliability demands, as demonstrated by the JEDEC JESD47 qualification. On top of that, the SHT45 is compliant with the relevant healthy building standards RESET® and WELL Building Standard™.
