The device comes in a small package, and is a capacitive-based device that uses an integrated heating element to dissipate moisture and condensation. The sensor integrates multiple digital features, allowing for the use of programmable input thresholds without a microcontroller to monitor the system. The HDC2080 sensor can also initiate measurements without input from a microcontroller. It offers a typical humidity accuracy of ±2 percent and a typical temperature accuracy of ±0.2 degrees C.
The sensor is designed for battery-operated systems and supports a supply voltage range of 1.62 V to 3.6 V. With an operating temperature range of minus 40 to 85 C, the sensors can be safely used in many applications.
The HDC2080 is supported by the HDC2080EVM, a simple plug-and-play platform that features an MSP430F5528 microcontroller and a USB interface.
