Security is primary concern for everyone. There are many ways to provide security at homes or in industries. But what if the security is assured irrespective of the person is inside or outside the house. This Project describes a design of effective security alarm system that can monitor the house with different sensors using GSM modem.
Home Security System is a security
system using wireless concept that monitors the status of each sensor
continuously. This project is mainly useful in homes, industries etc to
continuously safeguard homes and industries.
The main aim of this project is to
provide security to the homes using GSM technology. The security system
contains various sensors like reed switches which serve as door sensors,
vibration sensor, temperature (LM35), IR transmitter and receiver, LDE-LDR
pair, fire and gas sensors. The system continuously monitors the output of all
these sensors and if any of the sensors trigger, the controlling unit immediately
identifies the change in the output of the sensor and sends the predefined
message to the user mobile through GSM modem and also alerts the buzzer.
This
project not only provides security to the houses but also allows the user to
control the electrical appliances in the house. The electrical appliances like
lights, fan, TV etc can be operated just by sending predefined messages to the
modem.
