Motion sensor

Hi Cathodion,

 

you can use an IO-4, IO-16 or Analog IN Bricklet for this.

This Module has an open collector output with pullup (digital output!)

 

Simply connect 3V3, GND and one input to this module.

 

That's great!

Do you have any idea how long i can make the cables between the motion sensor and the IO bricklet? I'm wondering if i can use my 16-IO bricklet to connect a bunch of motion sensors on every floor of my house.

Sorry,

I guess the best will be to test this, but I would expect several meters. If you have problems with noise etc. try to decrease the value of the internal pullup by adding an external resistor in parallel.

I would try to achieve that the maximum current is flowing to

be maximum noise resistant.
