Testing an IR Sensor with REAL Fire! (Huge Mistake?)😲🧑‍🚒

​Can a simple and cheap $1 IR obstacle sensor actually detect fire? In this video, we test an ordinary IR sensor with real fire to build a quick and easy DIY Fire Alarm System using Arduino Uno! 🔥 Watch till the end to see how it works and how you can build one yourself at home. ​🧩 Components Used in this Project: ​Arduino Uno ​IR Sensor Module ​Buzzer ​Jumper Wires ​Breadboard / Power Source ​💻 Arduino Code: const int sensorPin = 2; // IR sensor module OUT pin to Arduino Pin 2 const int buzzerPin = 8; // Buzzer to Arduino Pin 8 void setup() { pinMode(sensorPin, INPUT); pinMode(buzzerPin, OUTPUT); Serial.begin(9600); } void loop() { int sensorValue = digitalRead(sensorPin); if (sensorValue == LOW) { digitalWrite(buzzerPin, HIGH); Serial.println("Fire Detected!"); } else { digitalWrite(buzzerPin, LOW); Serial.println("Normal"); } delay(100); } 👍 If you found this video helpful, make sure to Like, Share, and Subscribe to Robotic with Thidas for more awesome Arduino and robotics projects! ​#Arduino #FireAlarm #IRsensor #DIYProject #Electronics #SriLanka #RoboticWithThidas
