Fire alarm security system using the Nodemcu and Blynk app. This project is mainly based on IoT technology. Also, the system uses a flame sensor to detect fire. The unique feature of this system is that it receives a push notification to your smartphone in the event of a fire at the connected location. That function is performed by the Blynk app. We can use this project mainly for homes, offices, and factories.
When this system is powered on, the NodeMCU board connects to the Blynk cloud through the internet. Then, we can turn ON and OFF this system using the Blynk app interface. When the system is activated, the smartphone receives a push notification in the event of a fire. Afterward, the system goes back to normal.
