An IoT Based Smart Parking System Using LoRa

摘要

Internet of Things (IoT) plays a fundamental role in connecting the ecological things around us to a network. It helps us monitor the parameters of the things with the usage of sensors that are familiarize for remote sensing of the specific data and forward the information over the network cloud by means of Internet Connection. This paper centers around the idea of knowing the status of parking availability in a parking lot through Internet with the help of Internet of Things Technology. This uses Ultrasonic sensor to detect the vehicle in the parking slot, TTGO-ESP32-LoRa (transmitter) boards placed at different parking lots in different places to transmit the data. TTGO-ESP32-LoRa (receiver) receives the data which is placed near to the parking lots and also sends the slot information to IBM Watson IoT platform through WiFi protocol present in the Esp32 board. The status of the parking availability can also be viewed in the Android Phone.
