Air Quality & CO₂

Air Quality Sensors measure important environmental parameters such as CO₂ concentration, VOC gases and overall air quality. They are essential for smart home, indoor monitoring and modern environmental sensing systems.

The sensors can be easily connected to microcontrollers such as ESP32, ESP8266, RP2040 and Arduino-compatible boards. Many models support common interfaces such as I2C, UART and digital signals.

Typical applications include indoor air quality monitoring, building automation, smart home systems, offices and classrooms as well as industrial environmental monitoring.

When selecting a sensor, pay particular attention to measurement accuracy, sensor type (e.g. CO₂ or VOC), calibration and long-term stability, as sensor performance can vary significantly depending on the application.

Tip: Use the filters to quickly find the right air quality sensor based on measurement type, interface or application.

Air Quality Sensors measure CO₂, VOCs and air quality – ideal for smart home, indoor monitoring and IoT projects.
