An autonomous safety system that eliminates blind spots at U-turns using real-time sensor fusion and instant-response signaling.
Blind curves are fatal because they deny drivers the single most important asset: Time.
At 40 km/h, a car travels 11 meters per second. A driver needs 2.5s to react to a sudden obstacle. On a blind U-Turn, you often have less than 5 meters of visibility. The math simply doesn't add up.
of head-on collisions occur on sharp bends where visual confirmation is impossible until it's too late.
We replace human "guesswork" with millisecond-precision sensor fusion.
Our sensors "see" around the corner for you. By placing detectors 50m ahead of the curve, we effectively extend the driver's visual range, triggering warnings long before visual contact.
Faster warning delivery than human visual processing, giving drivers the critical distance needed to brake.
Ideal for narrow hairpin bends where oncoming traffic visibility is effectively zero.
Prevents collisions in dense city traffic where U-turns are obstructed by dividers or vegetation.
Manages blind corners in multi-level parking structures to prevent fender benders.
High-precision PIR sensors detect oncoming vehicles instantly, eliminating blind spots.
Smart logic triggers warnings on the opposite side, ensuring drivers are alerted before they turn.
Powered by Arduino Nano with optimized C++ code for millisecond-level response times.
// Constants for sensor & LED pins
const int pirPin1 = 2; // PIR sensor 1
const int pirPin2 = 3; // PIR sensor 2
const int redPin1 = 13; // Red LED 1 (Side 1 Alert)
const int redPin2 = 9; // Red LED 2 (Side 2 Alert)
void loop() {
// Read PIR sensors
int pir1 = digitalRead(pirPin1);
int pir2 = digitalRead(pirPin2);
if (pir1 == HIGH) {
// Car on Side 1 -> Warn Side 2
blinkRed(redPin2);
digitalWrite(redPin1, LOW);
}
else if (pir2 == HIGH) {
// Car on Side 2 -> Warn Side 1
blinkRed(redPin1);
digitalWrite(redPin2, LOW);
}
else {
// No Traffic -> All clear
blinkGreen();
}
}
If Side A has a vehicle, Side B immediately flashes RED to stop oncoming traffic.
If Side B has a vehicle, Side A flashes RED to prevent collision.
When no sensors are triggered, both sides show GREEN, allowing free flow.
