Description
Summary:This study aimed to design a motorcycle tire pump that uses an Android smartphone as a display of the pressure read during the pumping process, besides LCD. The motorcycle tire pump in this study is based on the NodeMCU so that the read data can be connected directly to the Android smartphone via WIFI (ESP 8266), which is already available on the microcontroller. The pressure sensor used is the MPX5700AP; the data read from the device during the pumping process can be monitored by using Blynk app that is available on the Google Play Store. The output accuracy of this sensor can be directly compared or verified with a standard pump pressure gauge, which is connected to the pump. Based on the test results, once the device is connected to the power source via adaptor, the pump works and the device provides data readings, which are displayed on the Blynk app. The defined threshold pressure is 28 psi, so the relay will switch off the pump automatically if the pressure is equal to or more than 28 psi. After testing the device for four times, the average accuracy was 0.75 %. This result indicates that the device can work quite accurately and can be used to pump the motorcycle with the appropriate pressure.
