Overview

The HDC1080DMBR is a digital humidity sensor with an integrated temperature sensor that provides high measurement accuracy at very low power. It features a 14-bit measurement resolution and an I2C interface, housed in a compact 3mm x 3mm WSON package. The device is designed to maintain excellent stability even in high-humidity environments, making it suitable for long-term deployments.

Why Choose This Part

The HDC1080 stands out for its ultra-low power consumption, drawing only 100nA in sleep mode and maintaining low active current even with the integrated heater. It offers a typical humidity accuracy of +/-2% and temperature accuracy of +/-0.2 degrees Celsius. The placement of the sensor on the bottom of the device provides better resistance against dust and environmental contaminants.

Applications

Smart Thermostats
Monitoring ambient environmental conditions to optimize HVAC control in residential and commercial buildings.
Cold Chain Logistics
Tracking temperature and humidity levels during the transport of sensitive goods like pharmaceuticals and food.
White Goods
Integrating environmental sensing into appliances such as refrigerators and air conditioners for moisture management.
Handheld Meters
Providing accurate environmental data for portable diagnostic and meteorological instruments.

Getting Started

Engineers can evaluate this sensor using the HDC1080EVM evaluation module, which interfaces via USB for rapid data logging. The device communicates over a standard I2C bus (address 0x40), requiring only two pull-up resistors and a decoupling capacitor for a minimal BOM. When soldering, follow the recommended reflow profile strictly to avoid shifting the sensor calibration.
