Arduino is an open-source electronics platform based on easy-to-use hardware and software while LabVIEW is a graphical programming telling how to connect functions and work with a variety of datatypes when constructing applications.This book will help beginners to get started with Arduino-based embedded systems including essential know-how of the programming and interfacing of the devices. Book includes programming and simulation of Arduino-based projects and interfacing with LabVIEW, based on practical case studies. The book comprises of total twenty five chapters with description, working model of LabVIEW and programming with Arduino IDE.

2.4 GHz RF Modem-Based Security System for Restricted Area

11.1 Introduction

This project is designed for monitoring the security of the restricted areas. The system is designed in two sections: (1) sensor node and (2) server. It is designed in such a way that it will sense any intrusion with the help of a passive infrared (PIR) sensor at the sensor node and communicated to the server wirelessly with a 2.4 GHz RF modem. At the server, a LabVIEW GUI is created to observe the system. Figure 11.1 shows the block diagram of the system.
