<![CDATA[When the pandemic occurred in 2019, disinfectant sprayers were needed for prevention, measuring body temperature at the entrance. The pandemic has been end, we still have to do this to prevent and be disciplined in healthy living. The research here will create a prototype of an automatic temperature detection and disinfectant device at the laboratory door. The laboratory location was chosen because mobility in the laboratory was conducive, if a trial was carried out it would not disturb the activity on laboratory. This spraying tool designed includes an HC-SR04 sensor for detecting the height of disinfectant liquid, a TCRT 5000 sensor for detecting a person's forehead which will take temperature measurements to the MLX90614 sensor. The buzzer sounds when the MLX90614 sensor detects a temperature above 370C. Spraying disinfectant liquid uses 2 0.2mm spayer nozzles, and a proximity sensor when detecting people passing by the spray booth.]]>
