We provide you with all industrial grade parts; 1 laser, 1 sensor, 1 mirror. This version does not come with a controller, or outputs. You have to interface the NPN outputs of this sensor to your own controller or device. Once installed it’s a great physical puzzle that must be navigated before proceeding in your escape room. Usually set up so that you have to power on the laser thru one puzzle, find the mirror, and then use the mirror and laser to shoot a specific spot in the room (sensor) to release a magnetic lock, or activate a solenoid door catch to get a clue or item needed.
