The MQ-2 gas sensor analog output pin(A0) is connected to the A0 ADC pin of the Arduino. Below picture shows MQ-2 gas sensor with Arduino and LCD on a breadboard. Arduino Code for MQ-2 Gas Sensor …
05/05/2016· Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ-2 gas sensor
26/05/2018· You can also use it with other microcontrollers like Arduino Uno R3 or any other. I will already posted a article on smoke detector interfacing with Arduino. You can check it below: Smoke sensor interfacing with Arduino Alcohol detector for factory Applications of MQ-2 smoke sensor. It has many application but some of them are given below: Domestic and industrial gas leakage detection ...
Gas sensors are quite useful devices for controlling pollutants in the air. Similar is the MQ4 Methane Gas sensor. The MQ4 sensor is a compact gas sensor which is highly sensitive to methane gas and less prone to alcohol and other gases. This methane gas sensor provides an output signal according to the sensed concentration of CH4 in the ...
About this project. MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response time to measure and take the data. Sensitivity can be adjusted by potentiometer behind it:
