Home Monitoring and Security system

Home security is becoming necessary nowadays as the possibilities of intrusion are increasing day by day .Lot of Security companies are available towards protecting house from getting vandalized or so. But still there is no much guarantee that the house be safe or even if the house vandalized, security personnel safe and sound to report to police nearby. This leads to property loss and damage. Lot of research been carried out employing sensors like PIR, Sensor Camera, GSM towards detecting the intruder at home. But the drawback in all these systems is that they are all expensive to be deployed integrated with LCD panel or Camera. Again with PIR sensor or Ultrasonic Sensor integrated with GSM, there is good possibility of false intruder detection based on line of sight cut by any entity and not necessarily an intruder. Currently homes in India still rely on security service personnel and no home security system been employed so far. So taking the above mentioned aspects into consideration, we here have developed an economical and affordable Home security system which have integrated the security component by making use of sensors like PIR, Temperature, humidity etc to sense the motion, change in temperature and humidity in room from normalcy rather relying on PIR sensor for change in motion only . The owner of the house is informed about any intruder by sending a text message by using of GSM module. All these activities are controlled by AtMega microcontroller of Arduino. This system would help all the users at any level of income to have one at their home and secure home from any vandalizing.
