The mq 2 gas sensor.
Mq 2 gas sensor arduino.
There are lpg cylinders which are used as a fuel source for the gas stove.
The mq series of gas sensors use a small heater inside with an electro chemical sensor.
Keeping this in mind in today s post i have worked on mq 2 gas sensor fc 22 powered and interfaced with arduino uno.
Sensitivity can be adjusted by varying the trimmer onboard.
Guide for mq 2 gas smoke sensor with arduino.
For detailed information for the mq 2 sensor refer to the datasheet.
The mq 2 sensor has 4 pins.
This smoke detector can be easily built onto a breadboard or a polka dot plate.
The best detection time for the sensor is should be 24 hours.
You can get this sensor for several.
Breath checker or early fire detection system mq2 gas sensor module is a great choice.
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.
The mq 2 smoke sensor is the one in the following figure.
Give your next arduino project a nose for gasses with the mq2 gas sensor module.
Alcohol carbon monoxide hydrogen isobutene liquefied petroleum gas methane propane and smoke.
Pin wiring to arduino uno.
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.
This module is provided with male header interface and can be easily interfaced with arduino mega using male to female type jumper wires.
Many a times disastrous accidents take place due to leakage of these cylinders in these situations we must administer proper care and safety.
Mq gas sensor type has many derived type for every certain gas.
Mq gas sensor type is the most popular gas sensor for hobbyist easy to get and of course very cheap.
The signal output voltage from the gas sensor will increase decrease when the sensor detects concentration of gas.
The output is an analog signal and can be read with an analog input of the arduino.
They are sensitive for a range of gasses and are used indoors at room temperature.
Here s the list taken from arduino cc website.
How to detect dangerous fumes and smoke.
The mq 2 gas sensor module is useful for gas leakage detecting in home and industry.
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.
This project uses the mq 2 sensor and an arduino to determine and detect different smoke intensities.
The mq 2 sensor is used to detect the levels of gas around the area so you can utilize this.
