BlueDot HDC1080 Board

The HDC1080DMBR is a high accuracy humidity and temperature sensor from Texas Instruments with a very low power consumption, making the device ideal for battery powered applications. The HDC1080 also includes a voltage supply monitoring and an integrated heater.

Features:

• High Accuracy. Measurement accuracy of up to ±2% accross the range of 20°C and 60°C. The HDC1080 also provides a 14-bit temperature sensor with a measurement accuracy of typically ±0.2°C between 5°C and 60°C.
• Wide Range Supply Voltage. The sensor operates from 2.7 V and 5.5 V at VCC, dispensing the need of voltage regulation. 
• Voltage Supply Monitoring. The sensor indicates when the supply voltage is less than 2.8 V, which is useful for battery powered applications.
• Low Power Consumption. It has a very low power consumption, up to 1.3 µA, which minimizes the impact of self-heating.
• I2C Communication. The sensor communicates through the I2C protocol using 0x40 as the address.
