Texas Instruments HDC2010 Humidity & Temperature Digital Sensor

Texas Instruments HDC2010 Humidity & Temperature Digital Sensor is an integrated sensor that provides high accuracy measurements with very low power consumption. The device comes in an ultra-compact WLCSP package. 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. These features, combined with programmable sampling intervals, low inherent power consumption, and support for 1.8V supply voltage, make the HDC2010 well suited for battery-operated systems.
