Product Descriptions

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 batteryoperated 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 HDC2080to 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.
