Parking Lot Availability IoT System Based on ESP8266 Platform

An electronic system for parking lot availability based on ESP8266 microcontroller is described in this article. Components of the system include a solar panel with rechargeable 18650 battery, an ESP8266 microcontroller with wireless communication and a magnetometer sensor. MQTT protocol is being used as communication for efficient data transfer between the parking sensors and the central server. Also, a web interface is developed for real-time parking lot tracking, which provides easy information accessibility on multiple platforms.
