Abstract

The research was conducted to analyze an automatic non contactless hand sanitizer dispensing machine. Many researches focus on manual dispensers which makes the hand sanitizer dispenser to be contaminated. The system consists of monitoring and alert features. The liquid level of hand sanitizer was monitored by using LED-RED while alerting the system to remind the owner to refill the hand sanitizer if the level been low. Other than that, PIR sensor was used to detect the presents of human in nearby and thereafter dispenses the hand sanitizer. An automatic hand sanitizer dispensing machine was developed using microcontroller as the main brain behind of the system operation. Hand sanitizer dispenser can be used in many public places and else. The system employed usage of an ultrasonic sensor, which senses the hand placed near it, and connected to electrically operated pump that pumps out the hand sanitizer liquid for its users. The IR Sensor is the photodiode used for sensing the human hand detection and it is used to control the motor pump from the liquid.
