₹1,562.32 incl. GST (₹1,324.00 + GST)
The CCS811 Air Quality Detection Sensor Module is a compact digital gas-sensing module designed for indoor air-quality monitoring. It uses the CCS811 sensor to detect a broad range of Total Volatile Organic Compounds (TVOCs) and provides equivalent CO₂ (eCO₂) readings for applications such as smart-home systems, air purifiers, HVAC monitoring, wearables, and IoT devices.
The module communicates through an I²C digital interface, making it easy to connect with popular development platforms such as Arduino, Raspberry Pi, ESP32, and other compatible microcontrollers. Its low-power design and compact form factor make it suitable for embedded air-quality monitoring systems.
VOCs can originate from many common sources, including paints, carpets, construction materials, electronic equipment, cleaning products, smoke, and human activity. By monitoring changes in TVOC and eCO₂ levels, the CCS811 can help provide an indication of indoor air-quality conditions.

Design and Construction
The CCS811 module integrates the digital gas sensor and processing circuitry into a compact breakout-board design. The onboard electronics provide a convenient interface for connecting the sensor to a microcontroller or embedded system.
The sensor uses metal-oxide (MOX) gas-sensing technology to detect changes in the concentration of target volatile organic compounds. Internal processing allows the sensor to provide digital air-quality information through the I²C interface.
Its compact construction makes it suitable for integration into portable devices, smart-home equipment, environmental monitoring systems, and IoT projects.
Working Principle
The CCS811 detects changes in indoor air composition using its metal-oxide gas-sensing element. When VOCs are present, they interact with the sensing material and cause changes in its electrical characteristics.
The sensor processes these changes internally and provides calculated TVOC and equivalent CO₂ (eCO₂) values through the I²C interface.
A connected microcontroller can read the sensor data and use it to monitor air-quality changes, trigger alerts, control ventilation, or display air-quality information.
The eCO₂ value is an equivalent estimate derived from sensor response, rather than a direct measurement of carbon dioxide concentration.
I²C Interface
The module uses an I²C interface, allowing it to communicate with a wide range of development boards using only the required power and communication connections.
It can be integrated with:
- Arduino
- ESP32
- Raspberry Pi
