SHT41-AD1B-R2

In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT41 ultra-low-power, 16bit relative humidity and temperature sensor offers the best price-performance ratio and improved accuracy specifications. Tape and reel packaging combined with suitability for standard SMD assembly processes make the SHT41 ideal for high-volume applications. The SHT41 builds on a completely new and optimized CMOSens® chip offering reduced power consumption and improved accuracy specifications. With the extended supply voltage domain from 1.08V to 3.6V mobile and battery-driven applications are the perfect fit. The super small-size realized in a robust DFN housing allows for integration in challenging designs while securing highest reliability demands as demonstrated by the JEDEC JESD47 qualification. Applications include air quality monitors, smart speakers / thermostats, dataloggers, smoke detectors, medical devices, inkjet and laser printers.
