Abstract :
The community's need for motorized vehicles as a means of transportation is
increasing. With the increasing number of vehicles, the number of accidents also
increases due to non-compliance with regulations or technical errors in vehicles
and drivers because vehicles are traveling at high speeds. In this study, the
authors created a design for speed monitoring and speed limiting devices based
on the Internet of Things. In this study, speed information monitoring tools and
speed limiters based on the Internet of Things will provide information if the
speed limit exceeds that specified by notifications on the Blynk application and a
Buzzer sound on the research tool. The speed information monitoring system and
speed limiter use the UBlok NEO 6M GPS module as a sensor to measure vehicle
speed, vehicle location when moving. This study uses the NodeMCU ESP8266
microcontroller to read sensor data as a data sender on the LCD, Buzzer and
Blynk application to provide information that the vehicle exceeds the specified
speed limit. The results of the study show that speed monitoring devices and speed
limiters can measure vehicle speed and provide speed limit notifications. Speed
testing with a speedometer testing tool shows an average error of 2.54% and an
average accuracy of 97.46% with 15 trials measured by the sensor on the
research tool compared to what is read on the speedometer. Testing sensor
response to the Blynk application, each test does not always have the exact same
response speed and delay because the signal on the internet network used is not
always stable or often changes.
