Product Details

describe:

The HDC2080 device is an integrated humidity and temperature sensor that provides high accuracy measurements at very low power consumption in a small DFN package. Capacitive-based sensors include new integrated digital functions and a heating element to dissipate condensation and moisture. The HDC2080 digital features include programmable interrupt thresholds to provide alerts and system wakeups without the need for a microcontroller to continuously monitor the system. Combined with programmable sampling interval, low power consumption and support for a 1.8V supply voltage, the HDC2080 is designed for battery powered systems.

The HDC2080 provides high-precision measurement capabilities for a variety 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, the HDC2010 offers a smaller CSP package option that is fully software compatible with the HDC2080.

For applications with strict power budget constraints, the automatic measurement mode enables the HDC2080 to automatically initiate temperature and humidity measurements. This feature allows the user to configure the AP6502SP-13 microcontroller into deep sleep mode, as the HDC2080 no longer relies on the microcontroller to initiate measurements.
