2% RH ultra-low-power digital relative humidity sensor, interrupt/DRDY

The HDC2080 device is an integrated humidity and temperature sensor that

provides high accuracy measurements with very low power consumption in a small DFN

package. The capacitive-based sensor includes new integrated digital features and a

heating element to dissipate condensation and moisture. The HDC2080 digital features include programmable interrupt thresholds to provide alerts and

system wake-ups without requiring a microcontroller to be continuously monitoring

the system. Combined with programmable sampling intervals, a low power consumption,

and a support for a 1.8-V supply voltage, the HDC2080 is designed

for battery-operated systems.

The HDC2080 provides

high accuracy measurement capability for a wide range of environmental monitoring

and Internet of Things (IoT) applications such as smart thermostats and smart home

assistants. For designs where printed-circuit board (PCB) area is critical, a

smaller CSP package option is available thru the HDC2010 with complete software

compatibility with the HDC2080.

For applications with strict

power-budget restrictions, Auto Measurement Mode enables the HDC2080 to automatically initiate temperature and humidity measurements. This feature

allows users to configure a microcontroller into deep sleep mode because the HDC2080 is no longer dependent upon the microcontroller to

initiate a measurement.
