This chapter discusses the working of a home automation system where
lights of the room are made ‘ON’ if a human presence is detected, with the help of
Scilab XCOS and Arduino I/O package. To understand the read/write operation with
Scilab XCOS, a system is designed to automate a room where lights will be ‘ON’, if
human presence is detected. Fig. (7.1) shows the block diagram of the system. The
block diagram comprises of power supply, Arduino Nano, motion detector sensor
(PIR), relay and Bulb.
Keywords: Arduino_1.1 Package, PIR sensor, Scilab.
