Home automation controller based on ATMEGA 328 Microcontoller

Abstract

The shortcomings of switches include; power loss due to mechanical contacts, difficulties in their access especially in darkness as well as wear and tear. Likewise, the problems of using a web server and mobile communication include network problems (distortion or attenuation) necessitates the development of infrared radiation home automation controller. Microcontroller- based home automation control was implemented using the passive infrared sensor (PIR) to sense an infrared radiation and output a voltage that serves as an input to the controller. The design was made to automatically switch ON any low power load connected between its output and the grid. The system operational mode is a self-automated mode that makes the controller capable of monitoring and controlling different appliances in the home automatically in response to the signal that comes to the sensor. However, the system was designed to maintain its output in the ON state as long as it senses the infrared radiation and then switch off when it senses no radiation in its vicinity. Flowcode V5 - software was used in the implementation of the system and the ATMEGA 328 microcontroller as system controller. Also, additional automation was implemented at the controller based on the ATMEGA 328 microcontroller for ease, security, and relatively low cost.
