Mq 2 Gas Sensor Arduino

Alcohol carbon monoxide hydrogen isobutene liquefied petroleum gas methane propane and smoke.

Mq 2 gas sensor arduino. They are sensitive for a range of gasses and are used indoors at room temperature. The signal output voltage from the gas sensor will increase decrease when the sensor detects concentration of gas. The mq 2 smoke sensor is the one in the following figure. This module is provided with male header interface and can be easily interfaced with arduino mega using male to female type jumper wires.

The mq 2 gas sensor module is useful for gas leakage detecting in home and industry. Mq gas sensor type is the most popular gas sensor for hobbyist easy to get and of course very cheap. For detailed information for the mq 2 sensor refer to the datasheet. The best detection time for the sensor is should be 24 hours.

Mq gas sensor type has many derived type for every certain gas. Guide for mq 2 gas smoke sensor with arduino. This project uses the mq 2 sensor and an arduino to determine and detect different smoke intensities. This smoke detector can be easily built onto a breadboard or a polka dot plate.

The mq 2 gas sensor. The output can be an analog signal a0 that can be read with an analog input of the arduino or a digital output d0 that can be read with a digital input of the arduino. Sensitivity can be adjusted by varying the trimmer onboard. This is a robust gas sensor suitable for sensing lpg smoke alcohol propane hydrogen methane and carbon monoxide concentrations in the air if you are planning on creating an indoor air quality monitoring system.

How to detect dangerous fumes and smoke. You can get this sensor for several. Here s the list taken from arduino cc website. The mq 2 smoke sensor is sensitive to smoke and to the following flammable gases.

There are lpg cylinders which are used as a fuel source for the gas stove. The mq 2 sensor is used to detect the levels of gas around the area so you can utilize this. The mq series of gas sensors use a small heater inside with an electro chemical sensor. The mq 2 sensor has 4 pins.

Mq 2 gas sensor arduino. The mq 2 sensor is a versatile gas sensor capable of detecting a wide range of gases including. This guide shows how to build a smoke detector that beeps when it detects flammable gas or smoke. Gas sensor with give an voltage output that increases with concentration.

Keeping this in mind in today s post i have worked on mq 2 gas sensor fc 22 powered and interfaced with arduino uno. Pin wiring to arduino uno. The output is an analog signal and can be read with an analog input of the arduino.
