Mouser Electronics, Inc., the industry’s leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components™, is now shipping the SHT4xA relative humidity/temperature sensors from Sensirion. The SHT4xA are 16-bit, high-accuracy, automotive-grade digital sensors for measuring relative humidity and temperature with different accuracy gradings, explicitly developed for the most demanding automotive reliability application requirements.
The Sensirion SHT4xA relative humidity/temperature sensors, available from Mouser, are designed for operation in harsh automotive environments, like accelerated lifetime tests at 85°C / 85 %RH. The SHT4xA sensors are AEC-Q100 rated and feature a powerful, integrated, on-chip heater with advanced onboard diagnostics for self-decontamination and periodic creep compensation in applications with prolonged high humidity. The SHT4xA sensors achieve accuracy tolerances of ±2 %RH and ±0.2°C from 0 %RH to 100 %RH at -40°C to +125°C, with operating voltage ranges of 2.3 V to 5.5 V.
Suitable for surface mount technology (SMT) processing, the SHT4xA sensors’ four-pin, dual-flat-no-leads package offers different accuracy classes, with I2C or pulse-width modulation interfaces, and with optional wettable flanks, enables automated optical inspection of the robust DFN package.
The SEK-SHT40A-AD1B temperature evaluation kit, also available from Mouser, is used to evaluate the SHT40A sensor. The kit includes three SHT40A sensors on an FPCB and a one-meter-long RJ45 adapter cable. The SEK-SHT40A-AD1B evaluation kit is designed to work with the Sensirion SEK-SensorBridge environmental sensing kit.
