Introduction
This analog gas sensor - MQ2 is used in gas leakage detecting equipment in consumer electronics and industrial markets.
This sensor is suitable for detecting LPG, I-butane, propane, methane, alcohol, Hydrogen and smoke. It has high sensitivity and quick response.
In addition, the sensitivity can be adjusted by the potentiometer.
Note: this module should be used together with EASY plug control board.
Features
- Connector: Easy plug
- Power supply: 5V
- Interface type: Digital and Analog
- Wide detecting scope
- Simple drive circuit
- Stable and long lifespan
- Quick response and High sensitivity
Technical Details
- Dimensions: 56mm*20mm*18mm
- Weight: 9g
Connect It Up
Connect the EASY Plug analog gas sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.
Upload the Code
Below is an example code. Open or drag below code to Mixly Blocks and upload.
What You Should See
Done uploading the test code, open the serial monitor and set the baud rate to 9600, you should be able to see the analog value.
Adding OLED Display
If you want to display the gas analog value more convenient, you can add OLED screen.
Hookup Guide
Test Code
What You Should See
Upload success, you should be able to see the analog value is showed on the OLED screen.
