Digital humidity and temperature sensor boasts high accuracy at low power

Mouser now stocks the HDC2080 humidity and temperature digital sensor from Texas Instruments. Providing high accuracy and low power consumption in a compact package, the sensor is ideal for a wide range of IoT and environment-monitoring applications. The sensor is a capacitive-based device that utilises an integrated heating element to disperse moisture and condensation. The sensor combines multiple digital features, providing for the use of programmable input thresholds to produce system wake-ups and alerts with no need to rely on a microcontroller to monitor the system. The sensor’s low power consumption enables developers to place their microcontrollers in deep sleep mode because the sensor can begin measurements without input from a microcontroller. The high-performance sensors provide a typical humidity accuracy of ±2% and a typical temperature accuracy of ±0.2C. The sensor is intended for battery-operated systems and supports a supply voltage range of 1.62V to 3.6V. With an operating temperature range of -40V to 85C, the sensors can be safely used in applications such as smart home devices, smart thermostats, home appliances, HVAC systems and inkjet printers. This digital sensor is supported by the HDC2080EVM, a simple plug-and-play platform that provides an MSP430F5528 microcontroller and a USB interface, enabling for easy communication between the HDC2080 sensor and a PC. The module’s integrated software graphically logs humidity and temperature data, and the module also enables access to the sensor’s configuration registers.
