Abstract: In this paper, a Multi level home security system using Arduino mega and GSM has been proposed. The fundamental capacity of this security framework is to recognize the presence of person and make the client alert about it at whatever point it is essential, by sending instant message to client's cell phone-number, enrolled already. In the essential stage, presence of any individual will be detected by a Pyroelectric (PIR) movement sensor and from that point forward, the individual should enter the correct secret phrase through a keypad. Oneself created secret key assurance gives a twofold sided advantage to this framework viz. any obscure individual should demonstrate his/her personality by entering the correct secret word to the security framework. Each time a secret key is utilized, it lapses, and another secret phrase gets produced by the framework and is shipped off the enlisted versatile number. The ongoing insurance has been performed utilizing a GSM SIM800L module which sends and gets instant text messages between client's cell phone and microcontroller for example Arduino mega. This security framework has given minimal effort and less convoluted home security insurance conspire by distinguishing any unapproved section to our home or whatever other spot that should be gotten.
