Arduino Based Security System using Passive Infrared (PIR) Motion Sensor

Abstract

Technological advancements are so fast as of now to make individuals need consistently to be inventive and trigger to make something new which can be applied and can utilize rapidly and for all purposes and control from close range and distance. There has been drastic increase in theft and burglary, robbing of houses, stores, shops and banks etc. This has also increased the number of violence and crime related activities which occur on a daily basis, in which lots of lives and monetary loses have been recorded. This research focuses on how to configure a simple home security framework using a PIR sensor(Passive Infra-Red) in light of a microcontroller. This safety will work if the PIR (Passive Infra-Red) sensor recognizes any individual that would not like to go into the house, and afterward themicro-controller process and instructs a mobile phone to send an alarm signal in theform of Short Message Service (SMS). After the program was successfully uploaded to the circuit, a test was carried out to determine if the PIR worked perfectly and it came out with positive results as it detected motion. As a motion was detected, the sensor became active, therefore gave a signal to the Arduino which gave an output signal to the led and thereby making the buzzer to sound an alarming noise.
