Applied Internet of Things (IoT): The Prototype Bus Passenger Monitoring System Using PIR Sensor

Monitoring passenger data in bus transportation fleets using the IoT concept. Factors that influence passenger monitoring are human counting errors and the accuracy of objects detected by sensors. The IoT system uses PIR (passive infrared) sensors and monitoring with mobile apps is a solution to overcome this, because the use of PIR sensors in the IoT system can only detect movements made by humans alone. The developed IoT system also implements a GPS module to be able to find out the location of the bus. Wemos D1 R2 will automatically send data collected from the results of detection by the PIR sensor and coordinates obtained by the GPS module to the Firebase database via the internet network. The monitoring application will display data stored on firebase on a mobile device. So that monitoring of bus passengers can be done quickly. Experiments on the research show that when the object's motion approaches the PIR sensor, it will not consistently detect the presence of passengers.
