Description: 1. MQ-2 is a Gas Sensor Module capable of detecting Hydrogen (H2), LPG (Propane), Methane (CH4), Carbon Monoxide (CO), and Smoke. This pack includes 25 units. 2. Design: The module features a heated filament sensor that reacts chemically when exposed to specific gases, altering the resistance that is then read by an analog input pin on an Arduino or any other microcontroller. 3. Easy Integration: Connects easily to Arduino and other microcontrollers via analog input pins (0-5V DC). No additional power source is required for the sensor itself. 4. Versatile Applications: Ideal for gas leak detection, air quality monitoring, automation systems, and safety applications such as fire alarms or propane detector systems. 5. Calibration: The sensor requires a simple calibration process using known gas concentrations to ensure accurate readings. It comes with a built-in reference LED that assists the calibration procedure. 6. Operating Principle: The resistance change caused by the presenc
