Abstract

A tool has been designed that can detect low, medium and full water levels. The series of tools designed is based on the NodeMCU ESP8266 microcontroller as the CPU. Because the water level detection tool still uses the Atmel, Atmega, Arduino Uno family microcontrollers as the CPU. The tool is designed to use a magnetic switch water sensor module as a water level detector, a NodeMCU ESP8226 microcontroller as a CPU, an LCD as a low, medium and full information display, a buzzer as an alarm sound signal generator indicating that the water is full, an LED indicator as an indication of the water level level. low, medium, and full. The designed tool can detect the height of the water level in the embankment. The LCD displays low information if buoy water sensor 1 is submerged in water, buoy water sensors 2 and 3 have not been submerged in water. The LCD displays information if the buoy water sensors 1 and 2 are submerged in water, the buoy water sensor 3 has not been submerged in water. The LCD displays full information when the float water sensors 1, 2, and 3 are submerged in water.

Abstract

ABSTRACT To improve motorcycle security when parked so that it is not easily stolen by thieves, a two-wheeled vehicle security system is designed using RFID and programmed buzzers. The tool is designed to use an Arduino Uno module, an RFID reader module, a relay module, an RFID card and a key chain. The Arduino Uno module functions as a CPU, the RFID reader functions to read RFID contents in the form of a card and in the form of a keychain, the relay module functions as a breaker and connector for electric current. Testing of two-wheeled vehicle security system tools using RFID and programmed buzzers has been carried out. The test results show that the contents of the RFID code can be read, both in the form of cards and key chains. RFID, whose code can be read, is entered into a program that is uploaded to Arduino Uno's flash memory. RFID in the form of a card and key chain which has been entered into the contents of the code into the program which is uploaded to Arduino Uno can turn off the machine and activate the buzzer, turn on and turn off the buzzer.
