HDC1000 Click Board™

IC/Module: HDC1000 sensor

HDC1000 is a humidity measurement sensor that also performs a temperature measurement. Offering high precision measurement at low-power consumption, it measures humidity based on a novel capacitive sensor. The sensing element on the bottom part makes HDC1000 resistant to dust, dirt, and similar contaminants.

low-power Consumption

The low-power consumption features make the device suitable for battery or power harvesting applications. Since, the HDC1000 sensor operates in two modes: sleep mode and measurement mode. In the sleep mode, it operates at a typical 110nA of current consumption, which makes the averaged current consumption minimal. Furthermore, the low-power consumption minimizes any self-heating.

I2C Serial Bus Address Configuration

HDC1000 Click Board™ communicates with the target board MCU through I2C lines. The HDC1000 sensor operates only as a slave device on the I2C bus interface. A pair on on-board jumpers enable the user to specify the slave byte address, with four to choose from. The slave address byte contains seven address bits besides a direction bit that specifies the intent to perform a read or write process.
