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 capacitivebased

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 wake-ups 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.
