In this project we will make project using 89s51. In this project we will sense the accident and our system will automatically send sms of location on our mobile no. In this project we will use GPS to monitor current location. GSM modem to send SMS. Then sensor on that side will detect the car using Reed sensor. When sensor will get signal from car having magnet, then it will give signal to microcontroller 89s51. Mirocontroller will display that station LCD connected with it. So wherever our robotic car will go oursensor will read it and Display ON . We will use 16*2 LCD for this purpose. We will connect REED sensor for car detection. We are using IC89s51 because we studying it in degree. We know about it. We will connect sensors on port 1 and LCD on port0. Register select pin of LCD on p2. 5, READ/WRITE on p2.4, Enable on p2.3. port 0 is open collector port so we will connect 10k register array with it. In this project we will use readymade robot. And use reed sensor for detection of robot.
