This project uses an MQ2 gas sensor, relay module (for motor or exhaust fan), buzzer, and LEDs to create a complete gas leakage detection and alert system using Arduino. When gas concentration crosses ...

This project is based on reading analog values from the MQ2 gas sensor using an Arduino. The analog readings are mapped to corresponding gas concentration levels using logarithmic plotting, following ...

Abstract: The application of sensors in smart homes using Arduino to control equipment such as lights, fans, alarms, and so on. Sensors used in Arduino include LDR, Ultrasonic, DHT11, and MQ2. LDR is ...

Abstract: LPG is an alternative fuel used for daily use. Due to its low cost and ease of installation. This article covers an Arduino-based gas detection system that uses an Arduino UNO R3 board and ...

In today's lecture, we will design a project in Proteus, where we will Interface Gas Sensor with Arduino. I will provide the complete code and simulation. Gas sensors are widely used in fire alarms, ...
