Control the distance! The Distance sensor is triggered only when an object is at the correct distance from it. Make players stand in a certain place to solve the puzzle.
The maximum load of the feeback connector is 50 mA. If you want to connect something with a higher current load, connect an external power supply - then the maximum load is 1A.
Connect the Distance sensor to the Universal puzzle controller via included Ethernet cable.
Connect the Universal puzzle controller to a power supply.
Fix the sensor to a surface. Then, place an object (or a person) in front of it at the right distance.
Push the teaching button to save the current distance to the object (or the person). The sensor will be triggered every time it detects something at the same distance.
Use the knob to control the margin for error (how accurate players have to be in terms of the exact distance).
The Distance sensor detects objects at a distance up to 4 m (13 ft) but its “field of view” is shaped like a cone (15° angle), so the bigger the distance, the more objects or people can interfere.
