Development of Motorcycle Brake Oil Control System Using Arduino Uno R3 Based Pressure Sensor

An alarm or reminder has been successfully designed to remind us when it is time to fill the brake fluid so as to avoid accidents when riding a motorbike with electronic components which are arranged, including Nex motorbike, Dot-3 brake fluid, Arduino Uno, Psi100 oil pressure sensor, red LED, Step down DC to dc, Resistor 220 0hm. The alarm was designed on the motorbike to serve as a reminder to fill the brake fluid before it decreases. In this research, calibration was carried out on the measuring instrument used so that the output produced by the sensor was the same as the digital measuring instrument, with an accuracy percentage level of 94.11%. The alarm system works when the pressure is low, the pressure sensor will read and process it on the Arduino, after processing the condition will be changed according to the pressure read by the sensor so when it is low the Arduino relay will provide voltage to the LED so that the LED can light up as a warning sign that the brakes are not working. good for use, and vice versa, when the brake fluid is full or meets standards, the relay will not be active and the motorbike will remain stable or can be used as usual.
