Overview ：The HDC1080 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The HDC1080 operates over a wide supply range, and is a low cost, low power alternative to competitive solutions in a wide range of common applications. The humidity and temperature sensors are factory calibrated.
Features: The relative humidity accuracy of HDC1081 is ± 2%, and the temperature accuracy is ± 0.2 ° C. It has excellent stability under high humidity. With 14 bit measurement resolution, 100 nA sleep mode current. The power supply voltage of HDC1080 is 2.7 V to 5.5 V. The average power supply current is 710 nA 1sps, measured by 11 bit RH; 1.3 µ A @ 1sps, 11 bit RH and temperature measurement. The equipment covers an area of 3 mm x 3 mm. I2C interface.
Power Consumption：One of the key features of the HDC1080 is its low power consumption, which makes the device suitable inbattery or power harvesting applications. In these applications the HDC1080 spends most of the time in sleep mode: with a typical 100nA of current consumption in sleep mode, the averaged current consumption is minimal.Its low consumption in measurement mode minimizes any self-heating.
Device Functional Modes：The HDC1080 has two modes of operation: sleep mode and measurement mode. After power up, the HDC1080 is in sleep mode. In this mode, the HDC1080 waits for I2C input including commands to configure the conversion times, read the status of the battery, trigger a measurement, and read measurements. Once it receives a command to trigger a measurement, the HDC1080 moves from sleep mode to measurement mode. After completing the measurement the HDC1080 returns to sleep mode.
Applications: HDC1080 can be used in the following equipment, such as HVAC, intelligent thermostat and room monitor, white goods, printers, handheld instruments, medical devices, and wireless sensors.
Description
Description: The HDC1080 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The sensing element of the HDC1080 is placed on the top part of the device. Measurement results can be read out through the I2C compatible interface. Resolution is based on themeasurement time and can be 8, 11, or 14 bits for humidity; 11 or 14 bits for temperature.
The HDC1080 operates over a wide supply range, and is a low cost, low power alternative to competitive solutions in a wide range of common applications. The humidity and temperature sensors are factory calibrated.
