PROTOTYPE INTERNET OF THINGS (IoT) ON ANDROID-BASED DOOR ACCESS
The use of conventional locks is currently less practical because they have to be carried when traveling and if the owner wants to open the door, he must come directly to the door. In today's fast-paced and automatic era, people often feel tired when they have to come directly to open the door because of the many activities and activities they do. This encourages the author to be able to overcome this problem by designing a tool that is more effective and efficient by utilizing the Internet of Things (IoT). This system is designed using a Wemos D1 Mini microcontroller and Smartphone Android-basede which is a remote control media for room door access. smartphones Android will be installed by the blynk application which is the controller to open the door, then the Wemos D1 Mini which is the control center for supporting components such as Magnetic Switch , Solenoid Door Lock, and Push Button . The trials that have been carried out give results that show that the system is working well.
