Smart Home Security and Intrusion Detection System

Conventional security systems which are the very common form of protection to lives and properties, have certain limitations such as real time monitoring and control of activities such as intruders in the form of human beings, fire, smoke, et cetera. These limitations in most cases result in high financial loss to properties and lives. This work involves the design and construction of GSM intelligent home security system for real time monitoring of different forms of intrusion. It consist of intrusion detection sensors, pressure, Smoke Fire, Gas and PIR motion , wireless sensors, programmable microcontroller in embedded C language, regulated power supply unit, proteus circuit simulator , relays, GSM modem, mobile phone, data acquisition node and an interface program development. The design calculation and analysis was carried out before it was modelled, simulated in proteus electronic simulator environment. When the PIR finds intruders in form of variation in temperature, gas leakage, pressure , the relevant sensing device s respond and the microcontroller sends encoded alarm signal to the wireless sensor network established in home. The moment the alarm signal is received, it will send alarm short message to the users owners of the building through GSM network immediately. The design analysis and calculations were carried out and finally, a positive result was achieved.
