Introduction

An air quality tester using NodeMCU is a project that utilizes the NodeMCU board and an air quality sensor, such as the MQ series, to monitor the concentration of gases in the air. The NodeMCU reads analog data from the sensor, converts it to a gas concentration value, and sends this information to a cloud service or displays it locally. This compact device can provide real-time air quality insights, making it a valuable tool for environmental monitoring and ensuring healthier living spaces. The project involves hardware connections and all the hardware design and manufacturing files.
