SMART HELMET

The Smart Helmet is an innovative IoT + safety project designed to improve road safety for bikers. It uses sensors and wireless communication to detect helmet usage, measure accident impact, and send alerts. With ESP32 as the controller, the smart helmet can also track location, monitor alcohol levels, and connect to IoT apps.

“A Smart Helmet ensures safety by detecting helmet usage, monitoring conditions, and sending IoT alerts in real time.”

Smart Helmet Working Principle

The Smart Helmet works by detecting whether the rider is wearing the helmet using an IR sensor. If not worn, the ignition remains disabled. Accident detection is done with an accelerometer/impact sensor. In case of a crash, ESP32 sends the GPS location via Wi-Fi/Bluetooth to emergency contacts or IoT dashboards.

First Project: Helmet Wear Detection

The helmet wear detection is the first step in this project. If the helmet is not worn, the ESP32 will block ignition. If worn, it allows the system to continue.

// Smart Helmet Wear Detection
int irPin = 5;     // IR sensor input
int ledPin = 2;    // Indicator LED

void setup() {
  pinMode(irPin, INPUT);
  pinMode(ledPin, OUTPUT);
  Serial.begin(115200);
}

void loop() {
  int helmetWorn = digitalRead(irPin);
  if (helmetWorn == LOW) { // Helmet detected
    digitalWrite(ledPin, HIGH);
    Serial.println("Helmet Worn - Ignition Allowed");
  } else {
    digitalWrite(ledPin, LOW);
    Serial.println("Helmet NOT Worn - Ignition Blocked");
  }
  delay(500);
}

Next Steps & Applications

After helmet detection, you can extend the project to accident detection, GPS tracking, alcohol monitoring, and IoT alerts. The Smart Helmet can be used for road safety, bike rental monitoring, and emergency accident response.
