Features:
Aluminum alloy, stainless steel material, support rod, speed measurement, energy measurement, speed energy, scrolling records and viewing average values.
This product is made by DIY, with the purpose of being simple, practical, accurate and durable.
It is mainly used to learn and experience the ability of single-chip microcomputer to process data at a high speed, and can measure the flight speed of various projectiles. Such as: table tennis, badminton, bow and arrow, physical acceleration experiment, free fall experiment of projectile, nerf toy speed test, children's soft toy, etc.
The core components adopt industrial-grade packaging, with stable performance and small errors.
This product has accurate speed for projectiles with a speed of 0-3000 m/s.
The utility model has the advantages of large effective sensing area, convenient use, high sensitivity and the like.
It is highly adaptable to ambient light and can be used indoors and outdoors at day and night.
You can save 80 sets of data, and you can see the average value.

notes:
This product is infrared radiation type, the light source has been integrated in the machine, no external light source is needed. Recommended for low-light environments. The darker the ambient light, the better the machine performance. Under outdoor use and strong light conditions, a hood must be added.
When measuring the velocity of the projectile at a higher speed. Please take appropriate protective measures. In order to prevent the projectile from rebounding after hitting the machine and causing damage.
When installing, pay attention to the marks on the left and right sides of the light bar, and the light bar with lights faces down.
Package includes:
1*Speedometer
3*Heat shrink tube light bar
4*Pure copper rod
1*Screwdriver
