1. INTRODUCTION

Today, security is becoming gradually wide spread a bit wise due to its several benefits, and with such advancement happening, the security of one’s home mustalsonotbeleftbehind.Thisprojectpresentsabasic application of the ESP32 cam module in the fields of security, automation, and the Internet of Things. in whichthecontrolsignaloftherespectiveGPIOpinofthe ESP 32 cam module is controlled by the content of the message received by the application client running on the ESP 32 cam module. The application used here is a cloud basedmulti platformmessagingapplicationcalled "Blynk".

Nowadays, robbery is on the rise. So, there is a great efforttobuildasafetysystemthatwillbrilliantlymanage this issue, keeping users away from terror about

residential security in all cases. The system is measured to be best only if it offers a shield and monitoring that guards in contradiction of many threats, protecting the home in contradiction of the elements as well as break insandhomeattacks.

Whenevertheuserisasleepatnightorawayfromhis residence for some reason, there is a chance that he is left unconnected with people who visit his place. These visitors may be known or unknown to the user. The planned system consists of a PIR motion sensor, a camera,arelay,andanelectricminilock.ThePIRsensor, which detects the presence of human appearance, will send a signal to the ESP 32 CAM Module, and an importantoperationofthecamerawillcaptureanimage. TheESP32CamModulewillsendthecapturedimageto the user through the Blynk application and also control the security lock (electric mini lock) with the help of a relayconnected to theESP 32CAMModule (Inbuild Wi fi)andcommentpassesthroughintheBlynkapplication.

Inevery“thing”hasitsuniqueidentitythat'swhatIoT (Internet of Things). It enables the connectivity with physical devices and allows user to transfer the information across the globe through the networks. The technology is playing an important role in day to days life. The main objective of our project is to make a system that will control the door employing a smart phone.this methodincludes variouscomponentssort of ESP32CAMModule(Inbuilt Wi Fi),PIR Sensor,Camera Module,Relay,voltageregulator,electricminilockanda Blynk(legacy) App for getting the notification on an AndroidDevice

4.2 PIR MOTION SENSOR

PIR (Passive Infrared sensor) is an electronic component that measures any quite object (person / animal) within the field. The window behind the lens is formed from IR transmissive material. The lens condensesilluminetosome6 7metersanditssensitive. it's a pin’s consisting of VCC, Ground and therefore the Output. The output is given to GPIO pins of ESP 32 CAM MODULE through 5V of power supply to the VCC. It is necessary to detect any intruder as early as possible in orderthatusercantakeimmediateactiontoshieldtheir properties.Thedetectionrangeofanormallow costPIR sensor based system is 10 m but this is often enough to hide most rooms with high ceilings.
