2021-02-05· MQ-6, AQ-2, MQ-306A, AQ-3. Selecting between Sensor type and module type. When it comes to measuring or detecting a particular Gas the MQ series Gas sensors are the most commonly used ones. These sensors can either be purchased as a module or as just the sensor alone. If you are trying to only detect (not measuring ppm) the presence of a gas ...
The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can ...
2021-02-25· 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.
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.
