MQ -5 Gas Sensor

The MQ-5 gas sensor is a device used for detecting the presence of gases like LPG, natural gas, and coal gas. Here are three brief points about it:

1. **Gas Detection**: The MQ-5 sensor can detect LPG, natural gas, and coal gas with high sensitivity and fast response time, making it suitable for gas leak detection in safety applications.

2. **Analog Output**: Provides an analog output voltage proportional to the concentration of the detected gas, which can be read by a microcontroller or analog-to-digital converter for monitoring and alert systems.

3. **Power Requirements**: Operates at 5V and has a preheat time of about 20 seconds to stabilize, ensuring accurate and reliable gas detection once operational.
