| Implementation Steps | 1. Connect all sensors - to ESP32 MQ-3 (alcohol), IR (helmet), and other components like servo motor, buzzer, and relay are connected to ESP32. 2.Power the circuit- Power supply (battery or adapter) provides 5V to ESP32 and sensors. 3.Helmet detection -IR sensor checks if the driver is wearing a helmet. If not detected, buzzer alerts and vehicle won’t start. 4.Alcohol detection - MQ-3 sensor senses alcohol in driver’s breath. If alcohol is detected, ESP32 cuts power using relay and buzzer sounds. 5.Speed control - If any unsafe condition occurs, servo motor limits vehicle speed. 6.Bluetooth monitoring ESP32 (inbuilt Bluetooth) sends data or alerts to phone for safety monitoring. 7.Testing and display Model is tested on small demo vehicle to show how sensors improve road safety. |
