Low cost wireless parking module design and implementation

Abstract

Finding a parking space in a large parking area becomes a problem for a driver these days. This paper presents a design and implementation for a low cost, wireless parking module, which contains of a parking sensor to detect a vehicle, and an LED display available parking space. This module uses a PING ultrasonic sensor and a NodeMCU as a microcontroller. The module connected wirelessly to the main server via a router. The module should cost less than average retail prices of similar module available on the market. A better approach for the vehicle detection scenario is also presented as a result.
