From the project
Hardware design, BOM, gerbers and 3D files for Air-quality-sensor-MQ135-breakout designed by Soldered Electronics.
The MQ135 sensor’s versatility allows it to be used for applications such as indoor air quality monitoring, gas leakage detection, and environmental sensing. While its main target gas is carbon dioxide (CO2), it is also sensitive to a range of other gases including volatile organic compounds (VOCs), alcohol vapors, benzene, smoke, and other harmful gases commonly found in the environment. By integrating the MQ135 sensor with appropriate electronic circuits and microcontrollers like Dasduino, you can create systems that provide real-time monitoring and analysis of gas concentrations, enabling…
