HDC2010 Humidity and Temperature Digital Sensor

Texas Instruments offers the HDC2010 low power humidity and temperature digital sensor

Image of Texas Instruments' HDC2010 Humidity and Temperature Digital SensorTexas Instruments' HDC2010 is an integrated humidity and temperature sensor that provides high accuracy measurements with very low power consumption in an ultra-compact wafer level chip scale package (WLCSP). The sensing element of the HDC2010 is placed on the bottom part of the device, which makes the HDC2010 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 HDC2010 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 1.8 V supply voltage, make the HDC2010 well suited for battery-operated systems.

The HDC2010 provides high accuracy measurement capability for a wide range of environmental monitoring applications and Internet of Things (IoT) such as smart thermostats, smart home assistants, and wearables. The HDC2010 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 HDC2010 is factory-calibrated to 0.2°C 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 -40°C to +125°C and from 0% to 100% relative humidity.
