Design Automatic Hand Sanitizer Microcontroller Based using Arduino Nano and Ultrasonic Sensors as an Effort to Prevent the Spread of Covid-19

Abstract

The government through the Ministry of Education and Culture (Kemendikbud) has made a decision to suspend teaching and learning activities in schools. The learning process that starts face to face directly in the classroom turns into distance learning /brave. However, the government decided to reopen schools in the Covid-19 corona virus green zone for teaching and learning activities for students. The opening of special schools in the green zone will be held in mid-July 2020. School openings must be opened with strict health protocols, no updated potential for new Covid-19 clusters in schools. This is a form of application of the "New Normal" that is being adapted to the people of Indonesia. Indonesian people must consider the existence of this corona virus pandemic with new normalcy, such as using a compilation mask outside the home, always using a hand compass tool and using a loudspeaker and distance measuring device. The purpose of this study was to make an automated hand sanitizer design as an effort to improve the delivery of Covid-19 in schools. Automatic hand sanitizer is useful to facilitate the hand sanitizer liquid out of the bottle, so it is more effective to use and does not run out quickly. This study uses an Arduino Nano microcontroller as the main control, a human hand detection sensor, and a servo motor as an actuator that will activate the automatic bottle. The mouth of the hand sanitizer bottle uses an elastic hose that leads to the part where the cleaning liquid comes out. This research uses the Research and Development (RnD) method. The result of this research is an automatic hand sanitizer with a large size hand sanitizer that can be mounted into a tool with a maximum of 500 ml. This automatic hand sanitizer will automatically release the hand sanitizer fluid which approves the sensor under the user's hand protective device.

covIoT: Integrated Patient Monitoring And Sanitization System

“…Long and Guangli [6] have proposed an infrared, non-contact human body tempera ture sensor that has a measurement error of less than 0.5 °C. Sumbawati et al proposed a system [7], in which the main control is an Arduino Nano microprocessor, with a human hand detection sensor and a servo motor acting as an actuator. Lee et al [8] built an automated sanitization tool that works with a variety of sanitizer containers, thus users need not buy a new liquid container when they change their hand sanitizer.…”

Pengaruh Jarak dan Sudut Tangan Dengan Sensor Terhadap Waktu Respon Penyemprotan Fluida Hand Sanitizer Otomatis Pada Mobil

“…Penyebaran virus corona, telah menyebabkan pandemi Covid-19 di dunia. Virus, yang pertama kali ditemukan di Kota Wuhan, Tiongkok pada akhir Desember 2019, telah berdampak luar biasa pada kelangsungan hidup warga dunia, karena virus ini menyebar dengan cepat kepada hampir seluruh warga negara, termasuk Indonesia (Sumbawati et al, 2020). Salah satu upaya untuk mengurangi penyebaran virus tersebut adalah dengan rajin mencuci tangan, menggunakan air dan sabun atau hand sanitizer.…”

“…Penelitian tentang pembuatan hand sanitizer untuk kebutuhan masyarakat umum (di luar mobil) sudah banyak dilakukan peneliti sebelumnya, sedangkan hand sanitizer untuk kebutuhan di dalam mobil belum ada. (Sumbawati et al, 2020) telah membuat hand sanitizer dan menyimpulkan bahwa hand sanitizer dapat bekerja dengan baik ketika jarak tangan 7 cm dari hand sanitizer. Peneliti lainnya dengan judul "Automatic Hand Sanitizer Container to Prevent the Spread of Corona Virus Disease" menyimpulkan bahwa hasil pengujian hand sanitizer otomatis dapat berjalan lancar dengan minimal kesalahan deteksi saat mentransfer data, Inframerah dapat mendeteksi gerakan hingga jarak 50 mm dan sensor ultrasonik dapat mendeteksi ketinggian air dengan jarak ke sensor 35 cm (Wanarti et al, 2020).…”
