The intention of our solution mentioned in the article was to create a simple device capable of measuring speed of a moving object. For various sports, such equipment is necessary during athletes' performance testing to determine progress. The designed device based on the ultrasonic sensor HC-SR04 in conjunction with Arduino is simple and inexpensive. The most important task in the implementation was to solve the synchronization between the measuring modules [1]. The nRF24L01 communication modules were used to synchronize the modules.
