Abstract This study aims to produce practicum tools that can measure the speed of the air. This tool uses the HC-SR04 ultrasonic sensor module as a sound wave transmitter and uses the Arduino UNO as a control system. The research method used is ADDIE. After the product has been developed, it is evaluated by conducting a validation test. Based on validation results, this practicum tool’s suitability has also been validated by the media expert. The following is the score achieved from each of the indicators, distance and time measurement score was 75%, appearance of practicum tool data was 100%, and clarify the concept was 75%. Therefore, the practicum tools as learning media to measure the air’s speed are fit for use.
