How To Make A Smoke Alarm For Your Kitchen Using Arduino?

A smoke alarm is an essential safety device for any household, especially in the kitchen where the risk of a fire starting is high. While there are many commercial options available in the market, you can also create your own smoke alarm using Arduino. Arduino is an open-source electronics platform that allows you to create interactive projects and devices. In this blog, we will walk you through the steps of making a smoke alarm for your kitchen using Arduino.

Materials Needed:
– Arduino Uno or any other microcontroller board
– Smoke detector module
– Buzzer
– Jumper wires
– Breadboard
– 9V battery and battery clip
– USB cable
– Computer with Arduino IDE installed


Step 1: Setting up the Hardware
First, connect the Arduino board to your computer using the USB cable. Then, place the smoke detector module and the buzzer on the breadboard. Connect one end of the jumper wire to the positive (+) pin of the smoke detector module and the other end to the 5V pin on the Arduino board. Similarly, connect the negative (-) pin of the smoke detector module to the GND pin on the Arduino board. For the buzzer, connect the positive leg to the digital pin 7 on the Arduino board and the negative leg to the GND pin.

Step 2: Uploading the Code to Arduino
Open the Arduino IDE on your computer and create a new sketch. Copy and paste the following code into the IDE:

void setup() {
pinMode(7, OUTPUT); //set buzzer as output

void loop() {
int smokeLevel = analogRead(A0); //read smoke level from sensor
Serial.println(smokeLevel); //output smoke level to serial monitor
if(smokeLevel > 600) { //if smoke level is higher than 600, buzz the buzzer
digitalWrite(7, HIGH);
} else {
digitalWrite(7, LOW);

The code above will read the analog data from the smoke detector module and check if it is above the threshold level of 600. If the smoke level is above 600, the buzzer will sound, indicating the presence of smoke.

Step 3: Testing the Smoke Alarm
To test the smoke alarm, you can use a lighter or a candle to produce smoke. Hold the flame near the smoke detector module and you should see the buzzer start to sound. If it doesn’t, check your connections and upload the code again.

Step 4: Powering the Smoke Alarm
To make the smoke alarm portable and battery-powered, you can connect a 9V battery to the Arduino board using a battery clip. Make sure to connect the positive (+) end of the battery to the Vin pin and the negative (-) end to the GND pin on the Arduino board.

Step 5: Final Touches
You can now place the smoke alarm in your kitchen. Make sure to test it periodically by producing smoke and ensuring that the buzzer sounds appropriately. You can also add LEDs to the setup to make the alarm more visually noticeable.

Congratulations, you have successfully created a smoke alarm for your kitchen using Arduino! This simple and low-cost project can potentially save lives by alerting you to the presence of smoke and preventing a fire from spreading.

In conclusion, creating your own smoke alarm using Arduino is not only a fun project for tech enthusiasts, but it also
