STERILIZER CHAMBER DESIGN WITH TELEGRAM-BASED INTERNET OF THINGS (IoT) APPLICATIONS

In order to reduce the spread of corona virus in office areas, malls or housing, a sterilizer chamber is installed. It used detect someone who will enter an area and he must be sterilized first by spraying entire body with disinfectant liquid automatically. By combining tool IoT technology, can monitored continuously at certain distance using sensor as detector which provide information one operators condition, about remaining liquid, number people have been sterilized. The system works providing on spray time 5 seconds level tube from 5-70. average output pin voltage 4.89 V when detects obstacle front NODEMCU receive ultrasonic HC-SR04. highest reaches 673.2 Mv, object 40 cm lowest 100.3 mV closest being cm.
