Automatic Paper Counter Machine Using Internet of Things and Arduino

The calculation of HVS paper is generally still done manually at printing and stationery stores. The manual calculation is very time-consuming and reduces the efficiency of store services if the amount of paper counted is more than 50 sheets. Therefore, a machine is designed that is able to perform paper calculations automatically and can be operated through apps on a smartphone and also manually with a push button. The method used in this research is to current sensors with linear regression, calculate paper using LDR sensors, and display the calculation results on the PCT-l apps and 16x2 LCD. The test results show that the operation of the machine with the smartphone can be done up to a distance of 50 meters. This machine is able to perform paper calculations with a calculation speed of 3 sheets per second. It can be concluded that the automatic paper calculation machine will be efficient if the number of sheets of paper counted is more than 50 sheets.
