Abstract :
The house is a place to store valueables that must be protected from
crimes such as a thieft. This device is designed to helps the homeowner to
monitor his house when the homeowner is not at home by sending notification
when there is a motion detected.
This security device using PIR sensor as motion detector that linked on
NodeMCU as Wi-fi module that can connects this device to the internet. This
device is equipped with LED and buzzer as indicator and can sends a
notification to user?s smartphone while there is a motion detected using blynk
platform installed on smartphone.
This device can detects human motion, animal motion and thing moved
but it can?t detects if there is a not transparent barrier. The detection range of
this device up to 900 centimeters with angle of detection up to 120o. The time
needed for send and receive notification on Blynk is about 0,3 ? 2,2 second
however the time can be affected by internet connectifity. The result of this
study is motion detector with PIR motion sensor that can improves security
system by implementing internet of things technology
