Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
- 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)
- 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.
- 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)
i bought 4 of these ir switches to make cool obstacles detection on robots. works well at short range.
