Garage Door Opener Sensor Reverse Engineer and Explanation
In this video I look at an infrared beam garage door sensor. The emitter board is analyzed to look at what kind of signal is generated. The sensor network is analyzed. The detector board is analyzed. Schematics of both are presented. These little sensors look basic but there is a lot going on.
