| HTU21D PERIPHERAL MODULE Digital Humidity and Temperature Sensor The HTU21D peripheral module provides the necessary hardware to interface the HTU21D digital relative humidity and temperature sensor to any system that utilizes Pmod compatible expansion ports configurable for I2C communication. The HTU21D sensor is a self-contained humidity and temperature sensor that is fully calibrated during manufacture. The sensor can operate from 1.5V to 3.6V, has selectable resolution, low battery detect, and checksum capability. The HTU21D has a low current stand-by mode for power-sensitive applications. Specifications • Measures relative humidity from 0% to 100% • Measures temperature from -40°C to 125°C • Humidity resolution selectable from 8 to 12 bits • Temperature resolution selectable from 11 to 14 bits • µA sleep current • 500 µA operating current during measurement only • ±3% accuracy • 12-pin Pmod compatible connector • I2C interface • Secondary 12-pin connector allows daisy chain • FPGA fabric available for download • µC code available for download • Built-in heater to remove condensation • Available with PTFE environmental filter over the sensor • Electronic ID code stored on chip HTU21D Peripheral Module Performance • Covers full humidity range of 0 to 100% RH • Broad temperature range of -40°C to 125°C • Use output data to calculate absolute humidity and dew point • Quick recovery from condensation 10 seconds • Fast response time to humidity changes 5 seconds typical • Fully calibrated and interchangeable • Recovers fully from condensation • Fast digital conversion time 14 mS typical Schematic SENSOR SOLUTIONS /// HTU21D PERIPHERAL MODULE HTU21D Peripheral Module Connector Pin Assignments 12C Communications System Plug Table 1 Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Connector J1 Signal Not Connected N/C SCL SDA Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Not Connected N/C SCL SDA Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Dimensions mm Expansion Socket Table 2 Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Connector J2 Signal Not Connected N/C SCL SDA Not Connected I2C Serial Clock I2C Serial Data Ground Power Supply Not Connected Not Connected Not Connected Not Connected Ordering Information Description HTU21D PERIPHERAL MODULE Part Number DPP301Z000 te.com/sensorsolutions TE Connectivity, TE Connectivity logo and Every Connection Counts are trademarks.
