Arduino-based Environmental Monitoring System with Gas and Air Flow Sensors

This template showcases a detailed circuit diagram of an Arduino-based environmental monitoring system. The system integrates various sensors, including gas sensors (MQ 135, MQ 7), a BME 680 air quality sensor, an air flow sensor, and a servo motor, all connected to an Arduino Mega board. The diagram illustrates how to power the system using a 12V battery with a buck converter and provides visual guidance on connecting the display module. This template is ideal for hobbyists and engineers working on IoT projects or environmental monitoring solutions.
