CCS811 and HDC1080 Air Quality Humidity and Temperature Sensor

This module contains a CCS811 digital gas sensor and an HDC1080 humidity and temperature sensor. This sensor module is intended for indoor use in combination with a microcontroller via an I2C interface.

The CCS811 module is a digital gas sensor that uses an integrated metal oxide (MOX) gas sensor to measure "Volatile Organic Compounds" (VOCs) from the air. The sensor can also measure "equivalent CO2" (eCO2).

The HDC1080 module is a humidity sensor with integrated temperature sensor that offers excellent measuring accuracy at very low power. Humidity and temperature sensors are factory calibrated.

Specifications:

• Supply voltage: 2.7 - 3.3V DC (3.3V recommended)
• CCS811:
  • Measuring range equivalent CO2: 400 - 29206ppm
  • Measuring range equivalent TVOC: 0 - 32768ppm
  • I2C address: 0x05 (default) or 0x5B (when ADDR pin is 3.3V)
  • WAK pin for low-power mode (connected to GND via 10K resistor by default)
• HDC1080:
  • Measuring range humidity: 0 - 100%
  • Humidity sensor accuracy: ±2%
  • Measuring range temperature: -20 - 70°C
  • Temperature sensor accuracy: ±0.2°C
  • I2C address: 0x40

Note: The CCS811 sensor uses a heating element to make measurements. This will cause the CCS811 sensor to heat up with continuous use and affect the measurements of the HDC1080 sensor. Therefore please check before purchase whether the used software supports limited measurements on the CCS811 sensor.
