Laser switch

Description

The laser switch is a phototransistor which filters a broad range of the visible specter. When the laser beam hits the receptor, the phototransistor sends a +5V message at the Signal input. Use:The laser switch can measure the same things as the photogate, the only difference is that the source is a laser, instead of a infrared led.
