Abstract
The proposed system makes use of vacuum pump which flushes out air to create vacuum and thus suction cup create pressure of 750 pounds. At first, the system is placed on the windshield of the car .The user then dials the OTP which is stored in microcontroller .The microcontroller then produces logic’1’ which goes into one of the input of relay .The other input of relay is from 12V DC battery .If the output of microcontroller is logic 1 then the signals before reaching relay, passes through ULN 2003A which acts as an amplifier and boosts the signal before reaching the relay. Then the relay switches the circuit to vacuum pump and vacuum pump flushes out air to create vacuum and then the suction cup sticks on the windshield and get locked .For unlocking the user has to dial the same OTP .Then the micro controller verifies that OTP from the previously dialled OTP .If they do not match then nothing will happen .If they match then micrcontroller produces logic’0’. Then the output of relay is logic’0’ and the vacuum pump stops and then the vacuum is released and the cups can be removed.
