The next generation in humidity sensing
As one of Sensirion’s industry-proven humidity and temperature sensors, the SHT40 offers an unmatched price-performance ratio on the global market. Tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT40 ideal for high-volume applications.
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. 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.
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. The year 2021 will also bring additional protection options to complete the portfolio, meeting even the most rigorous technological challenges. The on-package filter membrane ensures IP67 compliance for exposed designs, while the protection option ensures reliable conformal coating.
"As Sensirion has been setting the industry standard in humidity sensing for more than 20 years, the SHT4x strongly benefits from our vast application expertise. Our ambitions for the 4th generation are therefore limitless. They are reflected in the ultra-low power consumption, the unprecedented accuracy and the robust design allowing its use in the harshest environments", says Maximilian Eichberger, Head of Product Management Humidity and Temperature Sensors at Sensirion.
