PROTOTIPE ATAP STADION OTOMATIS BERBASIS IoT (INTERNET OF THING) DENGAN APLIKASI BLYNK

Stadium is the venue for sport activities like football, athletics, and and also be used for opening and ceremonial venue, and music concerts. The application of stadium roof is needed to anticipate unpredictable weather conditions that can hinder the running event. The stadium prototipe are made by using an electrical actuator in the form of a servo motor. The prototype have 3 input sensors in the form of LDR sensor, water level sensor, and DHT11 sensor, which function for read a weather condition around the stadium and for output using mini roof programmed using NodeMCU. Analysis of roof stadium performance testing is carried out with variables and parameters, and the test include the water level sensor test in reading weather conditions, servo motion test, DHT 11 sensor test to read temperature and humidity, and LDR sensor test to read conditions in the stadium. In the water level sensor test and the LDR sensor test there is no error. In the DHT11 sensor test error was found 0,6% for temperature reading and 1,9% error for humidity reading. In the servo motion test average success is 98,1% for first servo and 96,8% for second servo.
