When the flame sensor detects a flame, the Arduino sends a signal to illuminate the red LED, indicating that the fire alarm has been triggered. The green LED (D2) is connected to another digital ...

A comprehensive real-time fire prevention and monitoring system built with Arduino, Node.js, and modern web technologies. This system monitors flame, gas, and motion sensors to provide early warning ...

Abstract: The rising frequency and severity of fire events endangers human life and property. Firefighting is a momentous and perilous job. Fire detection and extinguishment are the hazardous job that ...

We don’t think we’d want to trust our fire safety to a robot carrying a few ounces of water, but as a demonstration or science project, [Tinker Guru’s] firefighting robot was an entertaining answer to ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
