Alat Pendeteksi Medan Listrik sebagai Sistem Keamanan Berbasis Internet of Things

Abstract

The electric field is a phenomenon that occurs due to the presence of an electric charge that occurs in a space around it. The availability of electrical energy to users or consumers is usually quite far away, so an electric power transmission/channel is needed. These electric and magnetic fields usually come from electrical systems and devices. There is always an electric field in a voltage and current installation system. The internet of things is a concept in which an object or object is embedded with technologies such as sensors and software with the aim of communicating, controlling, connecting and exchanging data through other devices as long as they are still connected to the internet. IoT has a close relationship with the term machine-to-machine or M2M. All devices that have M2M communication capabilities are often referred to as smart devices. This intelligent device is expected to help human work in completing various existing affairs or tasks. In this study, the nodemcu esp8266 microcontroller was used as a control system in the measurement process. The sensor used in this study is a hall effect linear sensor KY-024 which functions as an electric field detection. The application used is the BLYNK application as a data connection and IOT system. From the measurement results of the comparison of the KY-024 Hall Effect Sensor with the comparison, it is obtained that the average percent error in the above measurements is 1.88%. With an accuracy of 98.12%. The measurement results are explained, the danger indication is at an electric field value of 819(N/C) with a graphical output and no danger of 792(N/C) with a graphical output.
