The Internet of Things (Ardiuino UNO) has endless possibilities for public and private use. Automotive manufacturers are interested in Arduino UNO applications to improve vehicle safety, meet customer needs and ultimately deliver products that maximize profits. The healthcare industry wants to know how Arduino UNO can increase the speed and accuracy of communication. This article describes the possibility of installing a vehicle with technology that can detect the situation and immediately notify first responders. Thanks to this embedded system, accidents are prevented and necessary precautions are taken in this system. Ambulance and police agencies can easily locate the location as the location is sent to the smart device via a mobile phone connection along with a Google Maps link. Motors, buzzers, LEDs, etc. all these devices are connected to the central microcontroller. We will use blink sensors to detect sleep and by setting a time limit we will be able to warn the driver if he is sleepy. Temperature sensors help us detect engine temperature and we can warn the driver if the engine is hotter than normal. Alcohol sensors can help us detect whether the driver is drunk. If he is drunk, the car will sound an alarm and the engine will stop. The GPS6m module gives us the current position, speed, time and date of the vehicle at a particular location. After a simple accident, everything will be fine, so the driver in this situation can again show the ambulance and the police station. The Nodemcu microcontroller sends an email alert to the Ardiuino UNO with the location of the police control room or rescue team.The main purpose of our study is that the face sensor makes a sound and turns off the engine when the driver approaches the eyes or sleeps.
