LED Sensor Electronic Tracker with H-Bridge Drive

Posted on Feb 10, 2013

I decided to make a commercial surface mount PC board using the LED2 sensor concept. It is quite sensitive and can track to a few degrees of accuracy in bright sunlight. If a blocking shadow is used the accuracy is better then 1/4 degree, that`s about as good as you can get with an active feedback sensor. The board is a tiny .7`x1.4`.

This circuit uses power MOSFET drivers and is designed to operate satellite dish linear actuators, however most any DC motor can be used. The power drivers are capable of delivering about 10 amps of peak current, maybe more. When better transistors become
