The development of dispenser technology with various features is now rife in the community and there are already many dispensers that have made it easier for people to access refilled water in gallon packs. This language will refer to the Esp32 implementation as the core hardware to run the dispenser system. In this system, apart from the Esp32 as the core, there are supporting hardware devices including, Water pump, RFID (MFRC22), relay, 16x2 I2C LCD, Float sensor, buzzer, Flow sensor, 4x4 keypad, PSU all devices will run accordingwith the logic of the dispenser system. In the dispenser system using RFID tags to carry out inside the RFID tag, thebalance must be filled and registered on the dispenser server, the RFID reader will read the RFID and the RFIDtag data will be forwarded to Esp32 to be processed and sent to the server for data verification.
