Arduino based Fire Alarm – Circuit and Working. Fig. 2 presents the circuit diagram for the fire alarm using a flame sensor and Arduino Nano. The system is powered by a step-down transformer (X1), a ...

The flame sensor detects the presence of fire or flame based on the Infrared (IR) wavelength emitted by the flame. It gives logic 1 as output if a flame is detected, otherwise, it gives logic 0 as ...

Arduino Flame Sensor Interfacing Circuit Diagram. Now that we have completely understood how a Flame Sensor works, we can connect all the required wires to Arduino and write the code to get all the ...

This circuit is designed to provide a basic fire-sensing alarm system using a flame sensor and Arduino. When the flame sensor detects a flame, the red LED lights up, and the green LED turns off, ...

This is an Arduino project that implements a fire alarm system using a flame sensor. When a fire or flame is detected, it triggers an alarm (buzzer) and activates an LED to alert the user. The code ...

Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

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 ...

This paper presents the use of the Proteus environment for the study of Arduino-driven sensor circuits, designed to support electronics student education. A simulation model of sensor circuit has been ...
