ESP8266 GAS Sensor Project
This project demonstrates how to interface a gas sensor with an ESP8266 microcontroller to detect the presence of gas and display the status on the Serial Monitor.
Components Needed
- ESP8266 Microcontroller
- Gas Sensor (e.g., MQ-2)
- Jumper Wires
- Breadboard (optional)
Circuit Diagram
Circuit Setup
1.Connecting the Gas Sensor to ESP8266:
vcc: Connect to the 3.3V pin on the ESP8266.
gnd: Connect to the GND pin on the ESP8266.
DO (Digital Output): Connect to the D5 pin (GPIO 14) on the ESP8266.
Instructions
1.Code Upload:
Open the Arduino IDE with ESP8266 board support installed.
Install the necessary libraries if required.
Create a new sketch and paste the provided Arduino code.
Connect the ESP8266 to your computer, select the appropriate board and port from the Tools menu.
Upload the code to the ESP8266.
2.Testing:
After uploading the code, open the Serial Monitor.
You should see messages indicating whether gas is detected or not every 500 milliseconds.
Applications
Gas Leakage Detection: Monitor for gas leaks in residential or industrial settings.
Air Quality Monitoring: Track the presence of harmful gases in the environment.
Safety Systems: Implement gas detection in safety systems to trigger alarms or notifications.
Notes
Sensor Calibration: Calibrate the gas sensor according to the specific characteristics of your sensor to ensure accurate detection.
Power Supply: Ensure a stable power supply to the ESP8266 and the gas sensor.
Sensitivity Adjustment: Some gas sensors have a sensitivity adjustment potentiometer; adjust it according to your detection requirements.
