05-06-2019· The MQ-2 smoke sensor is sensitive to smoke and also responsive to the following flammable gases: LPG. Butane. Propane. Methane. Alcohol. Hydrogen. The resistance of MQ2 varies depending on the type of gas. The smoke sensor has a built-in potentiometer that adjusts the sensitivity of the sensor based on the accuracy of the gas you are testing.
Hooking up an MQ-2 (gas & smoke) sensor to an Arduino Uno via a breadboard. The wiring connection is important: Both A pins and the left H pin need to be connected to 5V. Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...
06-05-2016· The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.
27-08-2012· The first step is to download the latest version of the Adafruit Fritzing Library from GitHub The easiest way to do that is to click that big nice button up there, otherwise you can also go to the GitHub repository and manually download or clone. Next, open the archive and extract the file "" to a convenient spot (I use the Desktop).
Test water sensor. The program is very simple, the sensor is connected to the Analog A0 pin, if it is not immersed in water, the output value will be 0, as the sensor is immersed in the conductivity value increases as the output voltage increases. With the value read below the set threshold, the green LED lights up, the red LED is lit above.

There are LPG cylinders which are used as a fuel source for the gas stove. Many a times, disastrous accidents take place due to leakage of these cylinders, in these situations we must administer proper care and safety. Keeping this in mind, in today’s post I have worked on MQ-2 gas sensor (FC-22) powered and interfaced with Arduino Uno.
11-05-2020· Welcome aboard! There doesn’t appear to be a Fritzing part for a MQ-5, and there appear to be several versions around. A good start would be the url for the particular board that you need have to see if there is something that would do (there are Fritizng parts for other MQ gas sensors around and one of them may do.)
17-01-2018· O sensor MQ-2 , é um detector de gás e fumaça que pode indicar a presença de GLP (Gás liquefeito de petróleo, gás de cozinha), Propano, Metano, Hidrogênio e outros tipos de gases inflamáveis. Seu nível de detecção vai de 300 a ppm (partes por milhão), ajustáveis por um potenciômetro na parte de trás do módulo.
SENSOR DE FUGAS DE GAS MQ-2. El objetivo de este proyecto es el diseño, el desarrollo y la aplicación de un sistema de detección de gases. El circuito tangente está formado por un Arduino uno, y arriba está ensamblado directamente este SIM900, en el cual se conecta todos los pinos de entrada y salida, con un puente a cada puerto del escudo ...
