Abstract :
Hand sanitizers that are currently circulating are still manual, and if they are
circulating, there are still many manuals. people allow for the spread of a dangerous
virus or germ. So we need an automatic hand sanitizer that can reduce the potential
for the spread of the virus and keep it clean. The research methods are: potential
problems, information gathering, product design, product manufacturing, product
testing, product revision, and final testing. The tool is called Hand sanitizer
Automaticand detects running out of liquid through SMS notification gateway. This
tool is made to change thework system hand sanitizer that was previously manual to
automatic, and is more clean. This tool works when the sensor detects the hand is less
than 10 cm, then the servo will pull the lever and release the hand sanitizer. And
when the hand sanitizer out then the red light on the sensor liquid XKC Y25 DC
SIM900A dead and GSM module to send messages to mobile phones that hand
sanitizer is up needing to be recharged. Based on the results of the research that has
been done, hand sanitizers have been successfully made and can be used at the
Bengkalis State Polytechnic. From the result of tests that have been done 70 times,
the accuracy rate of the tool is 100 %.
