HDC2080DMBT

Texas Instruments' 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 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, low power consumption, and 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 through the HDC2010 with complete software compatibility with the HDC2080.In applications with strict power-budget restrictions, auto measurement mode enables the HDC2080 to initiate temperature and humidity measurements automatically. 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.Programmable 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 accuracy.<strong>Features:</strong> Relative humidity range: 0% to 100%, Average supply current (1 measurement/second): 300 nA: RH% only (11 bit), 550 nA: RH% (11 bit) + temperature (11 bit), Humidity accuracy: ±2% (typical), ±3% (maximum), Temperature accuracy: ±0.2°C (typical), ±0.4°C (maximum), Sleep mode current: 50 nA (typical), 100 nA (maximum), Supply voltage range: 1.62 V to 3.6 V, Temperature range: Operating: -40°C to +85°C, Functional: -40°C to +125°C, Available auto-measurement mode, I2C interface compatibility, Smart thermostats, Smart home assistants, Washer/dryers, HVAC, Systems inkjet printers
