PIR Stick for Tiny FX

A passive infrared (PIR) sensor stick that gives your Tiny FX projects the ability to trigger effects when motion is detected.

Humans and other warm objects emit heat in the form of IR radiation. This sensor uses changes in IR radiation to detect motion in front of it and sends out a simple digital signal that can be read by any microcontroller.

We designed PIR Stick to handle the very important business of triggering motion effects on our Tiny FX models so it comes with a cable that will let you plug it straight into the three-pin connector on Tiny FX. If you’re planning on using it with another microcontroller, you’ll probably want to pick up a JST-SH to DuPont cable to connect it up*. We also have loooooong JST-SH to JST-SH cables available if you want to position your PIR Stick further away from your model.

Notes

• Tiny FX Board is NOT included
• PIR Stick has no reverse polarity protection, so if you’ve wired it up yourself double check your wiring to make sure power is connected to + and ground is connected to -. It will get quite hot very quickly if you get the polarity wrong!
• The sensor has a preferred detection direction. For best results in a typical room, orient the stick vertically so that it can detect motion passing it horizontally.
