China Mq2 Smoke Liquefied Flammable Gas Sensor Module Methane Gas for Uno R3, Find details about China Mq2, Gas Sensor from Mq2 Smoke Liquefied Flammable Gas Sensor Module Methane Gas for Uno R3 Kuongshun Electronic Limited
Sep 25, 2020· Gas sensor MQ2 is used here with ATmega32 microcontroller to detect gas presence and display the level of the gas on LCD. MQ2 gas sensor can detect LPG, smoke and hydrogen gas, butane, CO2, alcohol etc so you can use it in many projects. Here we will simply display the level of LPG gas and Smoke in PPM(Parts Per Million) on LCD.
I''m using arduino uno, sim900 module, mq2 gas sensor and buzzer to create a gas sensor detector based on sms. I have to 2 option : 1. The mq2 gas sensor detects and send the result via sms to the number set in the code. 2. We can send a specific string to know the surrounding gas percentage and send the result to the specific number set in the ...

Sep 25, 2020· In the MQ2 pinout picture you can also see the potentiometer knob which is used to vary the sensitivity of the gas sensor. Wiring Diagram of MQ2 Gas Sensor with Arduino and LCD. The following diagram shows the wiring diagram of Arduino, 16x2 LCD with MQ2 gas sensor. The Arduino pins 13 to 8 are used for LCD.
The output is an analog signal and can be read with an analog input of the Arduino. The MQ2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, ibutane, propane, methane ,alcohol, hydrogen and smoke. Some modules have a builtin variable resistor to adjust the sensitivity of the sensor.
The 16x2 LCD display is connected to the Arduino (A0,A1,A2,A3,A4,A5) analog IO pins, where those pins are configured as digital in / out, where LCD operates at 4 bit data mode. If the display is not visible, adjust the Contrast pot (1K), to make it visible. Matrix key pad is arranged by push button switches in rows and columns.
