· MQ2 or MQ-2 is a sensor module that can be used to detect smoke or flammable gases at concentrations between 200 ppm – 10,000 ppm. Any gas that can be detected by MQ2 includes LPG, Hydrogen (H2), Methane (CH4), Carbon Monoxide (CO), Alcohol, Smoke (Smoke) and Propane. This sensor is designed for indoor use at room temperature. Usually applied ...
· But here I want to prove that Raspbery Pi can work with sensors too. That's why the MCP3002 analog-to-digital converter is necessary for this project. My problem now is the output value of smoke sensing system with Raspberry Pi based on the code above only represents one single value. It doesn't distinguish between smoke level, LPG level, and ...
· Example of the MQ2 MQ-2 Smoke / Gas Sensor Program with Arduino. using only the MQ2 sensor module to detect / create gas alarms that are detected at a certain level, the following article will present an example of a more detailed MQ2 program that measures the concentration of each gas detected according to the datasheet of the MQ2 sensor.
1. Raspberry Pi doesn't have any analog Pin so you will need an external ADC. so there are two option. get an external ADC with inbuilt amplifier. I will say look into ADS1115. the other option is go with a MQ2 sensor which comes with an on board Analog chip. So this will be the best way to go. you can look into this MQ2 gas sensor this one ...

· Arduino MQ-2 Smoke Alarm. The circuit we will build is shown below. So to power the smoke sensor, we connect pin 2 of the smoke sensor to the 5V terminal of the arduino and terminal 3 to the GND terminal of the arduino. This gives the smoke sensor the 5 volts it needs to be powered. The output of the sensor goes into analog pin A0 of the arduino.

· Due to the high sensitivity and fast response time of it. But, in this design, we used the MQ2 sensor for the smoke situation. This sensor has four outputs, namely, Vcc, ground, D0, and A0. Architecture. Firstly, to make an IoT based Air Quality Monitoring system will be collecting the data from the mq2 senor and send to NodeMCU. We will then be sending this data to aws IoT core using MQTT ...
· About MQ2 Smoke Sensor. The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG; Butane; Propane; Methane; Alcohol; Hydrogen; 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 ...
Raspberry Pi; Smoke Detector Alarm using MQ2 Sensor. 3 months ago 6 months ago by Fariha Zahid. In this tutorial, we are making a project of a Smoke detector alarm. We all know that there’s always a danger of things getting caught in a fire which can cause damage on many levels. There is always a smoke detector present inside every building or house, they are very useful as they provide …

· Some theory behind MQ2 The main component we'll be using here besides Raspberry Pi itself is MQ2 Gas Sensor Module. This gas sensor is perfect for measuring LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations in the air. These concentrations are represented as Parts-per-million (abbreviated ppm).

· MQ2 -> analog value -> MCP3002 -> digital value -> Raspberry Pi. Measure if the MQ2 sensors output have different values, measure with volt meter depending on the gas content. Add a potentiometer so you can simulate a input signal to the MCP3002. VCC to one end, input on MCP3002 to mid and GND to the other end.
MQ2 Smoke Sensor with Raspberry Pi. The smoke sensor we will use is the MQ-2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ-2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed to, the less voltage it outputs.
· The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG. Butane. Propane. Methane. Alcohol. Hydrogen. 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 digital output (D0) threshold.
