Smart Road Monitoring Radar with LTE Cat 1

measure the speed of cars, a radar, measure meteorological parameters

Droid Technologies designed and developed a smart road monitoring system for vehicle speed measurement, traffic analysis, meteorological monitoring, and cloud connectivity.

The device uses radar technology to measure vehicle speed and process traffic data in real time. It is based on an STM32F7 microcontroller and includes a touchscreen display for local configuration and diagnostics.

A built-in camera periodically captures road images and sends them with telemetry data to the AWS cloud via LTE Cat 1 using HTTPS. The system also supports OTA firmware updates.

For local communication between roadside devices, Zigbee mesh networking is used.

Key features:

• STM32F7 controller
• Radar-based vehicle speed measurement
• Traffic and weather monitoring
• LTE Cat 1 connectivity
• AWS cloud integration
• HTTPS data and image transmission
• OTA firmware updates
• Periodic camera capture
• Zigbee mesh networking
• Touchscreen GUI
• Custom PCB and embedded firmware

This project demonstrates Droid Technologies’ expertise in radar systems, traffic monitoring, STM32 firmware, LTE devices, Zigbee mesh, AWS IoT, camera integration, and intelligent transportation systems.
