Home Automation and security is an IOT project which basically has 2 windows apps, one working on Raspberry pi and controlling sensors and lights and other working on end user mobile phone through which user can control the lights and other appliances using speech or by clicking on buttons. We also have implemented security by Ultrasonic sensor i.e. whenever security is turned on and intruder will come in front of sensor an alarm will be triggered saying “Intruder! Intruder!” and at the same time a photo is clicked.
