COVID pandemic has influenced human life in various sectors.
Various attempts were made to reduce the virus transferring
by work from home, social distancing, and also including hand hygiene.
So far, most of the available hand sanitizers do not operate automatically.
This article aims to make an automatic hand sanitizer where soap
and water can come out automatically. Besides that, Automated hand sanitizer
will make notification to the owner, if the liquid has run out to the smartphone.
The infrared (IR)will sense the presence of heat and motion of the object and
 send data to the Arduino Nano so that it can activate the pump. If the water
height is less than 10 cm, The ultrasonic sensor will send data to node ESC8266
as a Wifi microcontroller to the output devices such as smartphones or PC based
on the Internet of Things (IoT). The results of the hand sanitizer testing that the
system can run smoothly with a minimum detection error of transferring data.
