In this project we are going to build a Simple Smoke Detector Circuit without using any Microcontroller. This circuit triggers the Buzzer whenever it detects Smoke or fire near by it.

Power up the sensor through Arduino and connect the A0 pin of the sensor to A5 of Arduino. Connect a buzzer and an LED in a parallel configuration. Connect their one end to the ground of Arduino and ...

In this Arduino IR sensor module tutorial we are explaining how to connect IR sensor module with Arduino Uno and write the code to get the IR motion sensor working.

Smoke Detector using Gas Sensor using arduino A Smoke Detector using a Gas Sensor for Arduino is a prime example of a project that assures beginners and hobbyists in learning how to develop a safety ...

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 ...

This optical smoke alarm is built around opto-interrupter MOC7811 and dual op-amp LM358. The circuit works off a 9V battery.
