    How to Use the MQ Gas Sensor Base PCB Board

    1. Connect Power

      • VCC → 5V (Microcontroller or Power Supply)
      • GND → Ground (GND)

    2. Connect to Microcontroller

      • DO (Digital Output) → Connect to a digital pin to detect gas presence (HIGH/LOW).
      • AO (Analog Output) → Connect to an analog pin for real-time concentration monitoring.

    3. Integrate with Code

      • Use a microcontroller (Arduino, Raspberry Pi, ESP32) to read gas concentration levels or trigger alerts when a threshold is reached.

    Package Includes:

    1 x Base PCB Board MQ Gas Sensors
