Cathodion Geschrieben August 16, 2012 at 13:42 Share Geschrieben August 16, 2012 at 13:42 Hey folks, I'd like to use a motion sensor in my home, and came across the following component: http://www.conrad.nl/ce/nl/product/172500/PIR-SMD-bewegingsmelder-3-12V2mA Can you create a bricklet for this, or explain how I can use an existing bricklet to connect this censor?

batti Geschrieben August 20, 2012 at 07:48 Share Geschrieben August 20, 2012 at 07:48 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.

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. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...

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. Zitieren Link zu diesem Kommentar Share on other sites More sharing options...
