Design of a Paper Money Counting Tool for the Infaq Charity Box of Syarikatul Anwar Mosque Based on the Internet of Things

Mosque financial management, especially the calculation of charity box balances, is often done in a homemade manner so that it is less efficient and prone to errors. This research designed a prototype of a smart charity box based on the Internet of Effects (IoT) using a TCS3200 color detector to detect the nominal amount of bank notes automatically. The detection data is displayed in real-time via a web or Android application. The system integrates an Arduino microcontroller with a detector and a communication module to provide high accuracy in detecting money. As a result, the system is able to reduce primary workload, increase transparency, and speed up the calculation of mosque balances.
