Question
Consider the development of a "through-beam" photoelectric sensor. A through-beam photoelectric sensor consists of a transmitting light source and a photo receiver. The transmitter and the receiver are lined up. When the beam is not broken, light from the transmitter hits the receiver and turns on the output transistor from the receiver. Their purpose is to detect objects as the objects break the beam. What are the operational parameters that must be determined before starting to design a through-beam photoelectric sensor?
Explanation / Answer
The operational parameters that must be determined in this case are the amount of electricity that will be used, the size of the sensor, as well as underwhat conditions the beam may be obstructed even though there is no object there to block it such as a fog for example, which may alter the trajectory of the beam coming back to the reciever. Among other things that could be considered are the cost and weight of the device as well.
Hope this helps, good luck.
