What is PIR Sensor

Chapter 12
Handbook of Research on the IoT, Cloud Computing, and Wireless Network Optimization
PIR stands for passive infrared sensor. PIR sensor detects a human being moving around within the range of 5m to 12m from the sensor. PIR sensor is fundamentally made of a pyro electric sensor, which can detect levels of infrared radiation. Show in Figure 13 (see Appendix). In this proposed work, PIR used for intruder detection. When an intruder is detected by PIR sensor then the camera will go high and capture the images and videos of that intruder and immediately send to the registered email address and website.

Abstract
The internet of things (IoT) is viewed as something that connects everyday objects like smart TV and smart phones. Automation is the future of human civilization. It's like operating various devices and machinery with minimum or no human intervention. In this chapter, home appliances and other electronic devices are proposed to be controlled over internet with the help of website or smartphone. Speech recognition technology has been implemented in this chapter which will help complete or partially visually impaired people or persons with physical disability. Smart CCTV concept has been developed in this chapter which will allow to operate the web camera whenever it detects motion and sleep at other times which will save energy as well as storage unlike current CCTV scenario. Also, smart CCTV captures images and video footage and provides the real-time status of the place via a registered email address, website, and mobile app. If you are outside, you can check the status of your home and be in line with it, and you will activate the home appliances from the web site and through speech.
