Description
The 3 to 1 trigger module is the latest in technological advances in sensors. Until now the bulky Adafruit IR Beam Breaker pair of diodes has had a reputation of being hard to conceal. In the KandR electronics 3 to 1 sensor module, the bulky electronics card has been moved down the wires so that it can be concealed in a larger structure or under the table away from the small sensor diodes.
It combines 3 of any of the KandR Electronics sensors so that the output is a single trigger wire. Typically you need a minimum of three cross track sensors to cover an area like a road traffic crossing train tracks. This is so that a gate controller can be signaled to lower the gates ahead of the train arrival for a more realistic operation.
Limitations with the input sensor pin on any controller cards is typically 3 connections. This allows you to connect 3 x 3 to 1 trigger modules to one input so you can have 9 sensors for sensing a train in a block. It can be used on our gate controller or our sound cards or any Arduino Adafruit computer digital input because it is a common collector circuit.
Check our video on the use and installation of sensors. There are many ways to configure them for achieving the results you need to create realistic operations of animatronics or sounds.
