It provides an analog output proportional to gas concentration, making it ideal for safety alarms and air quality monitoring systems. Its simple interface works with microcontrollers such as Arduino and Raspberry Pi.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eGas Detected\u003c\/td\u003e\n\u003ctd\u003eMethane (CH4), LPG, Natural Gas\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDetection Range\u003c\/td\u003e\n\u003ctd\u003e300 – 10,000 ppm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutput Signal\u003c\/td\u003e\n\u003ctd\u003eAnalog voltage (0-5V)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eHeating Resistance\u003c\/td\u003e\n\u003ctd\u003e33Ω ±5% at room temperature\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLoad Resistance\u003c\/td\u003e\n\u003ctd\u003e10KΩ (adjustable via potentiometer)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-gas-leak-alarm-kit-mq-2-sensor-led-and-buzzer-for-kitchen-safety\"\u003eGas leak alarm with buzzer and LED indicator\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eSmart kitchen safety system with IoT notifications (ESP8266\/ESP32)\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/pm2-5-air-quality-monitor-kit\"\u003ePortable air quality monitor with LCD display\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eMethane detector for biogas plants or mines\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eCompatible with any 5V microcontroller board, including Arduino Uno, Nano, Mega, and Raspberry Pi (external ADC required). It operates on 5V logic, so the analog output can be read directly by 5V ADC pins. For 3.3V systems like Raspberry Pi Pico, use a voltage divider or level shifter.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to ground, and AO (analog out) to an analog input pin. The MQ-5 draws about 200mA during heating, so use an external power source if powering from a board’s 5V regulator. Allow the sensor to preheat for at least 24 hours before the first use for accurate readings.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
