  • IR SWITCH

    posted by gozaki on 06/01/2012

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    - potentiometers allow range tuning
    - very small packaging
    - hole for bolt
    - on board LED to show detection ( you can disable this feature using a strap on the board)

    Cons:

    - need reverse engineering to understand how its work ( no user manual)
    - limited range as foreseen and mentioned. 30 cm is the max range i have reached.

    OtherThoughts:

    - doesn't work on black objects (seems normal, this is just black body theory i think)
    - this is well a switch. there is no modulation on the output
    - may be used for short range IRDA communications ( no protocol implemented inside)

    Bottomline:

    i bought 4 of these ir switches to make cool obstacles detection on robots. works well at short range.
