Break-Beam Sensor + Speaker

Posted July 11, 2012 by Chris

“About one month ago I had a request to write about break-beam sensors. So, here it is! Well, basically break beam sensor consists of two parts: transmitter and receiver. Transmitter emits light and that light goes to receiver. If that light beam between transmitter and receiver is broken by some obstacle, and receiver detects no incoming light even for a brief moment – it triggers an alarm.”
