SHT40I-HD1B-R2 is a 4th generation, high-accuracy, ultra-low-power, 16-bit relative humidity and temperature sensor at different accuracy classes. Its I C interface provides several preconfigured I C addresses and maintains an ultra-low power budget. The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments. The four-pin dual-flat-no leads package is suitable for surface mount technology (SMT) processing and comprises an optional on-package patented PTFE [1] membrane or a removable protection cap. Relative humidity accuracy up to 1.0%RH, supply voltage range from 1.08V to 3.6V Average current is 0.4 A (at meas. rate 1Hz), idle current is 80nA I2C FM+, CRC checksum, multiple. I C address Patented on-package PTFE membrane, fully functional in condensing environment Temperature accuracy is up to 0.1 C, variable power heater NIST traceability, JEDEC JESD47 qualification Mature technology from global market leader, removable protection cap Operating humidity range from 0 to 100 %RH, -40 to 125 C temperature range Product details Humidity Range: 0% to 100% Relative Humidity Humidity Accuracy: 2.5% RH Temperature Accuracy: 0.3 C RH Response Time: 4s Temperature Response Time: 2s Sensor Interface Type: - Sensor Output Type: Analogue Sensor Case Style: DFN No. of Pins: 4Pins Operating Temperature Min: -40 C Operating Temperature Max: 125 C Supply Voltage Min: 4.5V Supply Voltage Max: 5.5V Product Range: SHT4xI-Analog Series MSL: MSL 1 - Unlimited Other details Brand SENSIRION Part Number SHT40I-HD1B-R2 Quantity Each (Supplied on Cut Tape) Technical Data Sheet EN All product and company names are trademarks or registered trademarks of their respective holders.
