Two IR sensors placed on road at some distance. While vehicle passing on road first IR will detect and count will increase in nodemcu until second IR activated. When second IR activated count will stop. Based on this count value, nodemcu will calculate speed. If speed is more than desired limit thrn speed breaker will activate. Speed breaker controlled by servo motor as like shown in video. After some delay speed breaker will comes to normal position. This data will upload to IOT server. To get abstract visit above URL.
