Design of a Secure HAS Using Wi-Fi

Home automation is the residential extension of building automation and involves the control and automation of lights, air conditioning, ventilation, and heating (LACVH) appliances using the Internet of Things (IoT) and establishing a wireless connection to various electrical devices within our homes. The main objective of an internet of things is used to help old age people and specially challenged people to control electrical appliances, and the security will be provided to the entry point of the home. In this paper, we are using Wi-Fi to control the home appliances that means we can control the home appliances the devise from outside the Wi-Fi range through internet anywhere, any place, anytime. And it reduces human efforts and power efficiency. The proposed system also deals with the OTP (One Time Password) generation which will be used as home entry password for users. Data from all these sensors is continually received and processed by Arduino Uno board which acts as a microcontroller unit. In case of untoward situations, the Arduino will trigger an alarm and alert messages will be sent to user’s mobile via GSM. And the camera module to captures the attacker’s picture and sends to the registered mobile numbers. Thus the system ensures home safety as well as security
