Abstract

There are many incidents involving food processing machines that cause serious injury to human.This is due to fact that the machine does not equipped with safety features that can stop the machine when injury risk detected.To overcome this problem,a safety device is developed in this project that can detect human part touching the dangerous area,subsequently stop the machine.The device is developed by using touch switch circuit,forward-reverse motor circuit and Arduino microcontroller.To verify its efficiency,the device is installed to sugar cane juicer,where the rolling crusher is connected to touch switch terminal and forward-reverse motor circuit is connected to the motor of the machine. When human part (i.e. finger or hand) is touching the rolling crusher of the machine, the device is able to detect immediately the injury risk and stop the AC motor within 0.1s at motor speed 1600RPM.
