Features:
Aluminum alloy, stainless steel, support rod, speed measurement, energy measurement, speed energy, search record and view the average value.
This product is made by DIY, with the purpose of simplicity, practicality, precision and durability.
The main purpose is to learn and experience the ability of the single-chip microcomputer to process data at high speed, and can measure the flight speed of various projectiles. Such as: table tennis, badminton, bow and arrow, physical acceleration experiment, projectile free fall experiment, nerf toy speed measurement, children's plush toys, etc.
The core components are packaged in industrial grade, with stable performance and small error.
This product has accurate velocity for projectiles with a velocity of 0-3000 meters per second.
The utility model has the advantages of large effective sensing area, convenient use and high sensitivity.
Highly adaptable to ambient light, it can be used indoors and outdoors both day and night.
80 groups of data can be saved, and the average value can be seen.

Note:
This product is infrared radiation type, the light source has been integrated into the machine, no external light source is required. Recommended for use in low-light environments. The darker the ambient light, the better the performance of the machine. For outdoor use and bright light conditions, add a hood.
When measuring the velocity of the projectile at a higher velocity. Please take appropriate protective measures. To avoid projectiles bouncing back after hitting the machine and damaging it.
When installing, observe the marks on the left and right sides of the light bar, and the light bar with the light is facing down.
Packing list:
Speedometer*1 + 5 connecting rods + 3 light bars
