Gas Detector / Indicator (USB Powered) With Arduino
Using the MQ-4 gas sensor, a small, USB-powered gadget called a Gas Detector/Indicator (USB Powered) with Arduino Nano is made to identify and show the concentrations of gases, particularly natural gas or methane. The MQ-4 sensor is frequently used in applications for detecting natural gas leaks because of its high sensitivity to methane (CH₄).
Qualities:
Continuous monitoring with an easy-to-read display is known as real-time gas concentration monitoring.
USB-powered and portable: Ideal for a variety of settings.
Parts: Arduino Nano: Acts as the microcontroller for processing MQ-4 sensor data.
Methane in the surrounding environment is detected by the MQ-4 Gas Sensor, which then provides an analog signal proportionate to the concentration.
The gas concentration level is shown in a comprehensible way by a seven-segment LED display.
The complete system is powered by a USB power supply, which makes it portable and practical for a range of applications.
Principle of Operation:
The Arduino Nano receives an analog signal from the MQ-4 gas sensor, which monitors the methane content. The signal is read by the Arduino, which then computes the gas concentration by converting it into a digital value. The seven-segment LED display then provides real-time feedback by displaying the concentration level.
Uses:
Home and Industrial Safety: Notifies users of possible leaks to prevent gas-related mishaps.
Environmental Monitoring: Employed in garages and labs where methane detection is required.
