This kit SMS based vehicle ignition system is designed with an idea to use the mobile hand set as a long distance remote controller. The mobile sets are now a day’s used most widely and very commonly. The SMS can be sending to any mobile user of any service provider with no or a minimum charge.
In the kit SMS based vehicle ignition system this system is designed using a GSM modem. The GSM modem is configured as a receiver (for ignition control operation). The SMS sent by the user is written in a particular format. The controller receives the message and decodes it and identifies the task to be done.
In the kit SMS based vehicle ignition system oo control ignition (on or off), we have to send just a sms in a particular format, as soon as the sms gets received by the microcontroller; it fetches the particular data from the sms, and controls the ignition device accordingly. A proper message is also displayed on the LCD for the same (Optional). In the device interfacing part we will be needed a relay for the ignition device, and ULN2803 IC to interface the relay with the microcontroller. Acknowledgement in the form SMS will be sent to the user of the status of ignition.
