Generell
With this measuring device the actual speed can be determined.
Application
Lightning: Fast vehicles are indicated by the "speed trap".
However, no radar beam is used for measurement.
(The circuit can also be used without display)
Speed display: Like on some school roads, an display can be placed beside the road
Technology
The "flasher" is triggered by the speed of the vehicle (output is switched to minus).
You can setup a Servotiny or a speed-dependent Servo junction.
Fast vehicle drive straight forward, slower to be diverted to the parking lot or gas station
Function
The time is measured with 2 sensors, light barriers, reedswitches or Hallsensor.
The vehicle need to drive over the two sensors which have a distance of 15cm. The sensors must switch to minus.
Setup
2 Jumpers are used to set the scale: H0, TT, oder N |
