The sensor sends a signal to the switch contacts that are in the off condition resulting data input logic 0 to Arduino, the Arduino programmable timer which starts counting for 10 seconds. At the time of the count has been exhausted, the Arduino will transmit data signals to turn on the alarm and gsm module to be received through the mobile application, until the conditions in the state of the vehicle ignition is on or the key is removed.
