· Interfacing MQ2 Gas Sensor with Arduino. There are many gas sensors available in the market which detects different types of gases. In this article we are going to learn about interfacing MQ2 Gas Sensor with Arduino. This tutorial is for absolute beginners, where they can understand the concept of connecting a gas sensor with Arduino Uno.
The gas sensor needs about 5 volts of power in order to operate. This is done by connecting 5 volts to Vcc and GND. The Output pin gives out the voltage reading, which is proportional to the amount of smoke that the sensor is exposed to. Again, a high voltage output means the sensor is exposed to a lot of smoke. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...
· MQ-2 gas / smoke sensor interfacing with pic microcontroller. To interface this sensor with pic microcontroller, we only need to connect analog output pin of smoke sensor with analog input pin of pic microcontroller. I am using pic16f877a microcontroller in this tutorial. PIC16F877A microcontroller has built in 8 analog input channels.
· 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 ...
mq2 gas sensor can detect acetylene? can you please suggest one to identify it. Reply; Noor khokhar 7-2-2018 at 12:03. why we used MCP3008? i saw mq-135 sensor have already digital pin why we cannot direct digital pin. Reply. Veli 2-21-2019 at 18:30. That digital pin is not a serial communication pin. On the sensor’s circuit board, there is a potentiometer setting a threshold value. If ...
Interface single wire DHT11 sensor with 8051 and read the value of Temperature and Humidity from DHT11. Display these Temperature and Humidity values on the LCD 16x2.
Here we use an MQ-2 gas sensor that detects the LPG, Alcohol, Smoke, etc, gases. If there is a gas in the air the resistance between two electrodes of the gas sensor gets increased according to the gas presence. We use node MCU as a microcontroller or a wifi development board that reads the analog values from the gas sensor. In the code, we set the gas value [200]. The node MCU sends these ...
Gas sensors are designed to measure the concentration of gases in the environment. MQ2 gas sensor is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible.
