Product Overview
The HDC2010 is a Texas Instruments humidity and temperature sensor intended for digital environmental measurement through an I2C interface. It provides relative humidity measurement from 0% to 100% RH and temperature measurement across the specified device temperature ranges. The device supports selectable output data rates, including on-demand conversion, 5 Hz, 2 Hz, 1 Hz, 0.2 Hz, 0.1 Hz, 1/60 Hz, and 1/120 Hz.
The package is a 6-bump DSBGA/WLCSP with nominal dimensions of 1.5 mm × 1.5 mm × 0.675 mm. Pins include VDD, GND, ADDR, SDA, SCL, and DRDY/INT. SDA and SCL are open-drain I2C lines requiring pullup resistors to VDD, while DRDY/INT is a push-pull data-ready or interrupt output.
Key operating values include a 1.62 V to 3.6 V recommended supply range, ±2% RH typical humidity accuracy over the stated RH test range, and ±0.2°C typical temperature accuracy under specified temperature conditions. Current consumption depends on measurement mode, resolution, and rate, with specified sleep, measurement, startup, heater, and average-current values for low-duty-cycle sensor operation.
