In this project, am going to build a smoke detector sensor using Arduino that not only detects the smoke but also reads the level of the smoke in the air and displays it in the PPM. ...

This project is a fire and smoke detection system using Arduino. It's designed to detect fire, smoke, and high temperatures, and take automatic actions such as activating a fan, water pump, buzzer, ...

Optical smoke alarm uses MOC 7811 which is an optocoupler.The sensor designed for this device is based on the principle of scattering of infrared rays.The light coming from the light source passes ...

We built a Smoke Detector Circuit using Arduino and MQ2 gas sensor, ... Buzzer is connected at Pin D9. And LCD connections are same as Arduino LCD examples that are available in Arduino IDE (12, 11, 5 ...

As we have made a list of components that we are going to use in our project. Let us move a step ahead and go through a brief study of how these components work. Arduino Nano is a microcontroller ...

This circuit diagram illustrates a fire and smoke detection system using an Arduino UNO R4 WiFi, MQ2 smoke sensor, and a flame sensor (fire sensor). The Arduino is the central controller that receives ...

Working of this Smoke Detector Alarm Circuit is easy. In this project, we have used transistor operating properties to work this circuit as a smoke detector. As we already know that we have used a ...
