Low power humidity and temperature digital sensor provides high accuracy measurements

The Texas Instruments HDC2010 is an integrated humidity and temperature sensor that provides high accuracy measurements with very low power consumption, in an ultra-compact WLCSP (Wafer Level Chip Scale Package). The sensing element of the device is placed on the bottom part of the device, which makes the device more robust against dirt, dust, and other environmental contaminants. The capacitive-based sensor includes new integrated digital features and a heating element to dissipate condensation and moisture. The digital features include programmable interrupt thresholds to provide alerts/system wakeups without requiring a microcontroller to be continuously monitoring the system. This, combined with programmable sampling intervals, low inherent power consumption, and support for 1.8V supply voltage, make the device well suited for battery-operated systems. The device provides high accuracy measurement capability for a wide range of environmental monitoring applications and IoT such as smart thermostats, smart home assistants and wearables. It can also be used to provide critical temperature and humidity data for cold chain transportation and storage of perishable goods to help ensure products like food and pharmaceuticals arrive fresh. The device is factory-calibrated to 0.2C temperature accuracy and 2% relative humidity accuracy and includes a heating element to burn away condensation and moisture for increased reliability. The HDC2010 supports operation from -40C to 125C and from 0% to 100% relative humidity.
