The fence is the main part of a house in terms of security. The conventional fence is opened and closed manually by the home owner. In rainy conditions this will be very ineffective and inefficient because the home owner has to get out of the vehicle to open the fence. This problem underlies the idea of making an automatic fence opening and closing system using a smartphone by utilizing Internet of Things (IoT) technology. Smartphone is useful as a NodeMCU controller contained in the ESP8266 WiFi module via an internet connection to connect to the blynk application. Relay is used as a switch that will command the motor to rotate when it gets a command from NodeMCU. Changes in relay conditions will cause the 12volt 200rpm DC motor to rotate, so the fence will move opened and closed. The movement of the servo motor also causes the turnstile to lock after the fence is closed. In order for the system to work properly, the revolutions per minute (RPM) of the motor requires a supply voltage of 12V. When the fence is opened, the motor speed is 53RPM. When closed, the motor speed is 49RPM. In the process of locking and opening the fence, the servo motor takes about 2 seconds. Keywords: Fence, IoT, MotorDownloads
