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
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.
Programable temperature and humidity thresholds in the HDC2080 allow the device to send a
hardware interrupt to wake up the microcontroller when necessary. In addition, the power
consumption of the HDC2080 is significantly reduced, which helps to minimize self-heating and
improve measurement accuracy.
The HDC2080 is factory-calibrated to 0.2°C temperature accuracy and 2% relative humidity
