M. Department of Information Technology, Panimalar Engineering College, India B B.Buvaneswari We see that many automobile accidents are becoming a significant safety problem in the current society. Both human and animal lives are damaged by vehicle collisions. Due to breaking problems and quick response times when there is an impediment, more crashes happen. Therefore, the automated braking system for cars is presented in this work. Consumers are increasingly using their cellphones and the internet to make direct purchases rather than going to conventional brick-and-mortar establishments. Thanks to the internet, conducting business has never been quicker or easier than it is right now. A transmitter and a receiver are part of an ultrasonic system that is positioned in front of the vehicle. Life’s price cannot be calculated. This device measures the distance between obstacles using an ultrasonic sensor and notifies the driver when one is present. This essay also demonstrates the automated microcontroller's operation. The car will automatically stop when the safe separation distance is achieved. Its typical response time is 0.90 seconds, and its typical error rate based on the actual distance of the barrier is 11.2 seconds. 2022 2022 50 55 10.54216/IJWAC.040105 https://www.americaspg.com/articleinfo/20/show/1250
