Automatic Gate System with Autofocus Camera Using Node-RED

Abstract

Automatic gate system makes a property more secure and exclusive. In today’s era of automation, it is not just an advanced electronic feature to have an automatic gate but more often a need to provide high-end security. In this paper, an automatic gate system is designed which uses an autofocus camera to automatically recognize the license plate of a vehicle along with the vehicle type and model. The system uses Raspberry Pi 3B + and other sensors along with Node-RED for connecting the processor and different devices to form an Internet of Things (IoT) network. The use of autofocus infrared camera enables accurate recognition of vehicle license plates even with broken or distorted license plates. It also helps in detecting fake license plates with proper programming. Node-RED connects all the devices together by facilitating the flow of data from different sensors to the Raspberry Pi processor and also the uploading of data to an online database. This automatic gate system is easy to set up and has extremely useful features with robust body for unpredictable weather conditions. With the use of Raspberry Pi 3B + the processing is fast and execution is quicker with on-chip Wi-Fi module.
