Rancang Bangun Wadah Hand Sanitizer Pada Pintu Masuk Ruangan Menggunakan Node Mcu Berbasis Iot
ABSTRAK
Use of Hand Sanitizer at the entrance to the room as security for users who are in the room, so that the room is more sterile and all room users use Hand Sanitizer before entering the room. The sensors used in the manufacture of this tool use IR sensors and Ulteasonic sensors. The IR sensor functions to detect existing objects, in this study the object used is the hand. Ultrasonic sensors are used to detect the remaining liquid in the Handsanitizer container so that it can detect liquid when it is almost empty. The NodeMCU microcontroller is used as control and also access to the internet which can connect the system to the internet network. Data transmission is carried out, namely when the Hand Sanitizer liquid is almost finished, it will be sent via the Telegram application.
Kata Kunci: Arduino Uno, Sensor Ultrasonik, Sensor IR, Handsanitizer, LED.
