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 ...

In my professional life I have used many different gas analyzers for confined space entry as well as emergency response. These units are very expensive and require the user to be able to read the ...

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 ...
