This document describes a project that aims to add intelligence to existing security systems through human live detection and SMS notifications. It uses a human live detection sensor interfaced to a microcontroller to identify humans and verify their identity. When movement is detected, the microcontroller sends a signal to a connected GSM modem slave system, which then sends an SMS notification to a pre-stored phone number indicating human presence.

1. LIVE HUMAN DETECTION AND SMS INDICATOR
ABSTRACT
With the advent in technology, the existing systems are developed to have in built
intelligence. This is of greater importance in places where human identity is required. The
manual authentication and human intervention of the present systems has been replaced by
digital means. Of all the digital systems, Embedded Technology predominates as it
overcomes the drawbacks of all the existing mechanical and electronic systems.
This project “Human live detection and SMS remote indicator” d eals with giving
intelligence to the existing security system. In this the human identity is carried out using a
Human live detection sensor. The unique act as human attributes and can be checked out for
verification. The human live detection sensor is interfaced to the input port of the
microcontroller, which keeps track of the Identification. This setup acts as Master and
connected to slave system GSM modem via data port. The Master detects the movement of
the human body and sends a signal to slave via data port. Once slave receives the signal it
will send a SMS to the number which is already stored on that. The receivers will receive a
SMS from that GSM modem. This message will intimate the human place
