Audio Amplifier (LM386)Boosts the audio signal
Capacitor (100µF, 10µF)For sound filtering and gain
Potentiometer (10k)For volume control
Aux Cable / 3.5mm JackTo connect audio input
9V Battery / Power BankPower source
Small PCB or BreadboardFor assembling the circuit
Enclosure BoxFor a neat and safe finish

⚙️ How It Works

  1. The audio signal comes from the AUX cable.

  2. The LM386 amplifier IC boosts the weak audio signal.

  3. The amplified signal is sent to the 8Ω speaker, producing sound.

  4. A potentiometer controls volume manually.

 Gas Leakage Sensor Gas Leakage Sensor A gas leakage sensor is an essential electronic device that detects harmful gases such as LPG, methane, or propane in the environment. It is widely used in homes, industries, and safety systems to prevent fire accidents and ensure early warning of gas leaks. How a Gas Leakage Sensor Works Most gas leakage sensors, like the MQ-series (MQ-2, MQ-5, MQ-6) , work on the principle of semiconductor gas detection . The sensor’s surface changes resistance when it comes into contact with certain gases, and this change is measured by a microcontroller (Arduino, Raspberry Pi, etc.) to trigger alarms or safety devices. Applications of Gas Leakage Sensors Home Safety Systems – Detect LPG or natural gas leaks in kitchens. Industrial Safety – Used in factories to monitor hazardous gases. Automobiles – Helps detect fuel leaks in vehicles. DIY Electronics Projects – Popular for Arduino and IoT-based safety projects. Advantages of Gas Lea...
