Difficulty in finding parking spaces in free parking lots wastes time, fuel, and emissions. We design and implement a wireless system to count the number of cars and motorcycles in a parking lot based on Internet of Things. We deploy two sensor devices – one at an entrance and the other one at an exit of a parking lot. Each device consists of a NodeMCU ESP8266, an HC-SR04 ultrasonic sensor, and an MPU-9266 accelerometer. We use REST API to connect the sensor devices and users, who can get the parking status information from a web browser. To classify detected objects as cars, motorcycles, or people, we utilize a decision tree constructed using the C4.5 algorithm. © 2021 the authors.
