To face Revised Sep 13, 2020 free trade and global economic competition, every company is required to Accepted Sep 22, 2020 produce products that have good quality by the standards. By using an experimental method which is the development of this study aims to make a conductive material detector (metal detector) for the pharmaceutical industry, Keywords: the food industry, and security as compared to using conductive material sensors that are integrated with the Arduino microcontroller. Application ADC testing is carried out to find out whether the Blynk application on an android Arduino smartphone with Blynk on a Debian server that has been made previously Blynk Server runs well or not and the alarm system testing uses a buzzer and TI - Design of a conductive material detection system JF - IAES International Journal of Robotics and Automation (IJRA) DO - 10.11591/ijra.v9i4.pp292-299 DA - 2020-12-01 UR - https://www.deepdyve.com/lp/unpaywall/design-of-a-conductive-material-detection-system-CZ8qHFHoZR DP - DeepDyve ER -
