The Solar Radar Speed Sign with Smiley or Sad Face and Speed Display is an intelligent traffic-calming device designed to encourage safe driving behavior. It uses a built-in radar sensor to detect the speed of oncoming vehicles and displays it on a bright LED screen. Depending on the driver’s speed, the sign shows a smiley face 😊 for compliant speeds or a sad face 😞 for overspeeding, providing instant visual feedback to drivers.
Powered by solar energy, it operates efficiently without external power connections, making it ideal for highways, school zones, residential areas, and industrial sites.
