Detailed Description

• ID: hdc1000
• Name: HDC1000 Temperature & Humidity Sensor
• Category: temp
• Manufacturer: ti
• Link: http://www.ti.com/lit/ds/symlink/hdc1000.pdf
• Connection: i2c

Description in web-link above: The HDC1000 is a digital humidity sensor with integrated temperature sensor that provides excellent measurement accuracy at very low power. The device measures humidity based on a novel capacitive sensor. The humidity and temperature sensors are factory calibrated. The innovative WLCSP (Wafer Level Chip Scale Package) simplifies board design with the use of an ultra-compact package. The sensing element of the HDC1000 is placed on the bottom part of the device, which makes the HDC1000 more robust against dirt, dust, and other environmental contaminants. The HDC1000 is functional within the full -40 to +125 [degC] temperature range.

                  << "Temperature: " << mySensor.getTemperature(true) << std::endl;

        std::cout << std::endl;

        upm_delay(1);
    }
