Abstract

During the pandemic the learning process was conducted online and partly done face-to-face so that every day there are still students and employees who are in the campus environment. One of the prevention of covid transmission is done by spraying disinfectant when passing through the front gate of the campus. A design a prototype of an automatic disinfectant spray system and build a system on the prototype that can provide real time information related to monitoring the contents of the disinfectant tank by designing hardware. The results of the research built a disinfectant spraying automation system in front of the entrance gate of Universitas Musamus, to get results that prove that the system performance has been running as expected, there are several tests carried out such as tool testing and measuring the reading distance of the ultrasonic proximity sensor, and testing. sending SMS alert. How to provide information that the liquid in the tank has run out. Sensor sends a status signal for the disinfectant liquid level after spraying, a warning SMS is sent went the distance of disinfectant liquid and the ultrasonic sensor at a predetermined threshold.
