Turn-key PCB assembly services in prototype quantities or low-volume to mid-volume production runs

Show Your Talent by DIY a Sun Tracking Unit

Probably you saw Sun tracking system before; however do you have the urge to challenge yourself to make a Sun Tracking Unit?

First of all, get a tiny .7″x1.4″ PC board using the LED3X sensor concept. This circuit uses power MOFSET drivers, which most any DC motor can be used without any modification.

You might noticed that the power drivers are good enough of delivering about 50 amps of peak current or even more. The current will increase accordingly to the transistor. This mean the large power MOFSET, 72A when operated in low current, it will eliminates the needed for a heat sink on the transistor. Cool, isn’t it?

The duty cycle can easily adjustable from 0% to almost 100%. The function of duty cycle is to slow down the motor drive speed.

The LED Remote Sensor

The remote sensor can be configured in two ways:

1. The Single axis
2. The Dual axis

Besides that, it also exists in “parking” or “no-parking” on axes as well.

Hope you all will enjoy this fun DIY project. [Source]

  2. Hi
    what is the difference between this kind of sensors and LDR?
    is it better to use specially if Iam having 17watt solar panel.
