With the sensor you can switch your modells on/off.
The PIR Sensor senses the motion of a human body.
Step 1: Technical Data
Operating voltage range: DC 4.5-20V
Level output: High 3.3 V /Low 0V
Delay time: 5-200S(adjustable)
I use a darlingten power transistor 2N6387 as output driver. A 3 Volt Relais or a power MOSFET would be other alternatives.
The 2N6387 is strong enough for induktive loads like toys motors.
power transistor 2N6387
1x fischertechnik base plate 45x45 mm
2x M2 screw 20 mm and nuts
2x fischertechnik or Märlin 2,6mm plugs
1x Märklin 2,6mm socket for output
30cm triple cable
10x30 mm prototpye circuit board
Step 2: Implemetation
Cut the copper track on pin3!
Solder the Transistor and solder the board on the sensor.
Solder the (+) (-) cable on the board.
The collector is the output.
The load is between collector and operating voltage.
There must be no holes drilled. The screws fit into the slots.
Screw the plate with two nuts per screw.
Step 4: Action Video
The PIR is in the lower left corner of the model.
