In Today’s world, transport is essential to the public and with the rise in population accidently increased in the vehicle usage, this leads to more accidents. Most of the accidents occur due to the consumption of alcohol, the speed of the vehicle exceeds, or when the driver felt drowsy. There are many sensors that are used to detect. In this project we are using the alcohol sensor and eye blink sensor. These sensors are connected to the Node MCU ESP8266. Node MCU ESP8266 has the inbuilt Wi-Fi. These are placed on the PCB. The speed of the vehicle slows down when it detects the abnormal condition of the driver. The buzzer gives the beep sound when it detects the drowsiness of the driver and senses the alcohol detection. And also a notification message is sent to the mobile, by using the blynk application.
