3 Description
The 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 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 1.8V 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 pharma-
ceuticals 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.
