6/4/2021· One such sensor used in safety systems to detect harmful gases is the MQ2 Gas sensor. If you want to make an indoor air quality monitoring system, breath checker, or early fire detection system, the MQ2 sensor is a suitable choice. In this tutorial, we are going to discuss how to interface the MQ2 smoke detector sensor with Arduino and its code.

3/2/2014· Overview. This sensor module utilizes an MQ2 as the sensitive component and has a protection resistor and an adjustable resistor on board. The MQ2 gas sensor is sensitive to LPG, ibutane, propane, methane, alcohol, Hydrogen and smoke. It could be used in gas leakage detecting equipments in family and industry.

25/2/2021· This circuit is simple and can be easily made, it has a smoke sensor that detects any smoke around it and then activates a loud alarm to provide an indication. The smoke sensor used in this circuit is the MQ2 smoke/gas sensor.

22/12/2020· The MQ2 is one type of gas sensor, which can sense Smoke as well as LPG, Alcohol, and Methane. Arduino board is the main brain of this system that controls the whole system. The MQ2 sensor continuously measures Smoke levels in the air and sends data to the Arduino board. Then Arduino prints the Smoke level value on the OLED display in the PPM unit.

Give your next Arduino project a nose for gasses with the MQ2 Gas Sensor Module. This is a robust Gas sensor suitable for sensing LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations in the you are planning on creating an indoor air quality monitoring system; breath checker or early fire detection system, MQ2 Gas Sensor Module is a great choice.

MQ2 gas sensor has high sensitivity to propane and smoke, also can detect the natural gas and other flammable steam well. It is with low cost and suitable for different applications of detecting kinds of flammable gases. It is widely used in domestic gas leakage alarm, industrial flammable gas alarm and portable gas detector.

9/2/2021· MQ2. Get started with gas and smoke detector and Arduino. Calibration, value reading. The MQ2 is a sensor that allows gas or smoke detector at concentrations of 300 ppm to 10,000 ppm. After calibration, the MQ2 can detect various gases such as LPG, ibutane, propane, methane, alcohol, hydrogen and fumes. It is designed for indoor use at room ...

15/1/2014· MQ2 Smoke Sensor. MQ2 gas sensor can be used to detect the presence of LPG, Propane and Hydrogen, also could be used to detect Methane and other combustible steam, it is with low cost and suitable for different application. Sensor is sensitive to flammable gas and smoke. Smoke sensor is given 5 volt to power it.

11/6/2018· Smoke Detector with Arduino MQ2 Sensor. First of all, we need to connect some jumper wires between Arduino and MQ2 smoke sensor shield. Here’s the image of our Gas sensor and you can see, it has four pins in total. Vcc: We need to provide +5V. GND: We need to ground it.

16/11/2018· Arduino lesson – MQ2 Smoke Sensor Introduction. In this project, we will go over how to build a smoke sensor circuit with an arduino board. The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs.

14/10/2016· This circuit mainly uses MQ2 Smoke/Gas sensor and Arduino to detect and calculate the level of smoke. MQ2 gas sensor is also sensible to LPG, Alcohol, and Methane etc. This Smoke Detector can be ...
