8128 CCS811 + HDC1080 + BMP280 Gas Temperature and Humidity Indoor Air Quality

This three-in-one sensor module provides comprehensive indoor air quality monitoring by integrating three complementary sensors on a single board with an I2C interface. It is ideal for home automation projects, connected weather stations, or intelligent ventilation systems.

The CCS811 sensor analyzes volatile organic compounds (TVOC) and estimates carbon dioxide concentration (eCO2). The HDC1080 provides precise temperature and relative humidity measurements, while the BMP280 measures barometric pressure with high resolution.

Specifications

• Integrated sensors: CCS811 (gas/eCO2/TVOC), HDC1080 (temperature/humidity), BMP280 (pressure)
• Communication interface: I2C (default addresses distinct to avoid conflicts)
• Supply voltage: 3.3 V to 5 V (logic compatible with 3.3 V and 5 V systems)
• Low power consumption, suitable for battery-powered or energy-efficient microcontroller applications
• Compact form factor with standard pin headers for easy integration into breadboards or custom PCBs

This module is compatible with Arduino, Raspberry Pi, ESP32, and any microcontroller supporting the I2C bus. Dedicated libraries are available for each sensor (Adafruit_CCS811, Adafruit_HDC1080, Adafruit_BMP280).
