Abstract
Breaking the chain of community transmission is one of the best precautions to COVID- 19 spread. In this work, a novel automatic water dispenser and sanitizer with infrared human temperature sensor using Arduino for community spread chain breaking is proposed. In this work, an Infra-red PIR sensor is utilized to sense the human presence. After the defined period of human presence sensed by the sensor, the water pump will be ON for five seconds, which will pump water for five seconds to wash the hands and pause for 3 seconds to wipe the hands. After that, it pours the required amount of hand sanitizer from the sanitizer container attached to the stepper motor unit. During this process, the human temperature sensor also senses body temperature. If the temperature exceeds the limit (98.6 o F) it will forward the alert message to the doctor’s mobile phone using the GSM module also display an alert message in the LCD display attached with the processor with alarm.
