SHT4x Series Humidity and Temperature Sensors
Sensirion’s SHT40 4th generation of humidity sensing is ideal for high-volume applications
In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT40 offers an excellent price-performance ratio. Tape and reel packaging, combined with its suitability for standard SMD assembly processes, make the SHT4x ideal for high-volume applications. The SHT40 offers solutions for industrial, automotive, and smart tracking markets. The SHT43 sensor, being 3-point calibrated and ISO 17025 certified, is the perfect choice for smart tracking applications.
The SHT40 builds on an optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. With an extended supply voltage range from 1.08 V to 3.6 V, it is 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.
The high-accuracy versions SHT41 and SHT45 will be available in 2021. They feature typical and maximal accuracies honed even further, 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.
