The CCS811 CO2 sensor temperature humidity VOCs is an ultra-low-power digital device designed for accurate indoor air quality monitoring. It integrates a gas sensor and an 8-bit MCU with an analogue-to-digital converter (ADC), enabling the detection of gases such as carbon monoxide (CO) and a wide range of volatile organic compounds (VOCs).

This module is ideal for battery-powered equipment thanks to its low energy consumption. Its high sensitivity and fast warm-up allow reliable measurements in a short time. It also features an intelligent algorithm that calculates Total Volatile Organic Compounds (TVOC) and carbon dioxide equivalent (eCO2) values.

Key features

Ultra-low power consumption, suitable for portable and battery-powered devices.
High sensitivity and fast warm-up for accurate measurements.
Integrated intelligent algorithm for TVOC and eCO2 calculation.
I2C signal output for direct communication with main systems.
Metal oxide (MOX) sensors for indoor air quality monitoring.
Integrated microcontroller for data processing and first-class algorithm.
Integrated ADC for digitised, accurate readings.
Reset and interrupt control for greater flexibility in applications.

Typical uses

This sensor is ideal for electronics and Arduino projects that require environmental monitoring, such as smart ventilation systems, weather stations, home automation devices and indoor environmental control. Its easy integration via the I2C interface makes it perfect for developers and hobbyists looking to improve air quality in homes and enclosed spaces.

Compatibility

The CCS811 sensor module is compatible with Arduino platforms and other control systems that support I2C communication, making it easy to integrate into custom and professional projects.

Customer Questions & Answers

Which gases and environmental parameters can the CCS811 sensor measure exactly, and what are its detection ranges?

The CCS811 sensor measures carbon monoxide (CO), equivalent carbon dioxide (eCO2), total volatile organic compounds (TVOC), temperature and humidity (when integrated with additional sensors). The typical range for eCO2 is 400 to 8192 ppm and for TVOC, 0 to 1187 ppb. It does not provide absolute CO2 values, only estimates based on the presence of VOCs, which is important to bear in mind for critical applications.

What connection and voltage requirements does it need to work correctly on an Arduino board or similar?

The CCS811 typically operates between 1.8 V and 3.6 V (3.3 V supply recommended). It communicates via the I2C interface (SDA/SCL pins). It is compatible with most microcontrollers that support I2C. It is essential not to exceed the specified voltage to avoid permanent damage. Also check that the logic levels match between your board and the sensor.

Are there software libraries or compatible resources to make it easier to integrate the CCS811 into home air quality monitoring projects?

Yes, there are widely used open-source libraries for platforms such as Arduino, ESP32 and Raspberry Pi, making it easier to read and configure via I2C. These libraries often include examples for displaying both eCO2 and TVOC, and allow adjustments for calibration criteria in domestic environments. It is recommended to review the manufacturer’s documentation and the community resources before integration.

What gases does the CCS811 sensor detect?

The CCS811 sensor detects carbon dioxide (CO2), carbon monoxide (CO) and a wide range of volatile organic compounds (VOCs).

How do you connect the CCS811 sensor to an Arduino system?

The CCS811 sensor connects via an I2C communication interface, allowing easy integration with Arduino boards and other compatible systems.

Is the CCS811 sensor suitable for battery-powered devices?

Yes, the sensor has ultra-low power consumption, making it ideal for battery-powered equipment.

What is included in the CCS811 sensor package?

The package includes a CCS811-811 sensor ready for integration into air quality monitoring projects.
