Human Identification Based Smart Power Saver Using Raspberry Pi

Abstract

This project describes a new economical solution of home devices control system using Raspberry Pi processor. This control system consists of Raspberry Pi processor which acts as Control Unit, PIR, which is used to the Raspberry pi processor and Relays for device switching. The Raspberry Pi processor takes input from the PIR Sensor and processes this information and control the devices using switches ON/OFF with appropriate relays. The intelligent control software, which has been developed using Embedded Linux programming used to switch from one electrical device to another. The devices were fully controlled by the PIR sensor and by the control circuit with help of the relays. The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation. The Raspberry Pi has a Broadcom BCM2836 system on a chip (SoC), which includes an ARM1176JZF-S 900 MHz processor, Video Core IV GPU, and was originally shipped with 1GB of RAM. It does not include a built-in hard disk or solid-state drive, but uses an SD card for booting and long-term storage.
