    Humidity/temperature sensor works with MCU in deep-sleep mode

    The sensor allows for the use of programmable input thresholds to deliver system wake-ups and alerts without needing to rely on a microcontroller to monitor the system. Developers can place their MCUs in deep sleep mode, because the sensor can initiate measurements without input from a microcontroller.

    The sensors offer a typical humidity accuracy of ±2 percent and a typical temperature accuracy of ±0.2 degrees C.

    The sensor features an auto measurement mode to initiate humidity and temperature measurements, enabling efficient performance in applications with power-budget restrictions.

    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 applications such as home appliances, smart home devices, smart thermostats, HVAC systems and inkjet printers.

    The HDC2080 humidity and temperature digital sensor is supported by the HDC2080EVM, a platform that features an MSP430F5528 microcontroller and a USB interface, allowing communication between the HDC2080 sensor and a PC.

    The module’s included software graphically logs humidity and temperature data, and the module also allows access to the sensor’s configuration registers.
