A $3.77 waterproof case for Arduino Projects

Hi, I am always lurking through Walmart and Home Depot etc. looking for Stuff That Could Become Arduino Parts.

I found this "Waterproof floating Lantern" at Walmart and used it in a project HERE: It could be used for lots of other Arduino-based projects that need an outdoor case, batteries and maybe an on-off switch. Like remote temperature / humidity / Other sensing with an nRF24L01 radio, Wildlike sensor / Camera control. Etc. Etc. If anyone makes a project based on that case, please let me know and I'll add it to the ArduinoInfo.Info WIKI

I wonder if you mounted an IR range detector directly onto the inside of the lens it would still work and keep the project waterproof.

The interface between the air and the lens material will be almost totally reflective.

Possible to fill the gap with an IR conducting material? I have no idea what would be suitable.

Actually, I was referring to ultrasound as the project was obviously using that.

I haven't looked into IR rangefinders, which are a different thing entirely and presumably would work by measuring parallax. What Riva illustrated looks more like a proximity detector rather than a rangefinder.

So indeed these are parallax detectors, presumably what is used in (digital) cameras.

Obviously these should work just fine behind a glass or polycarbonate faceplate, needing only a plenum in between the two sensor units, extending out to the faceplate.

I was thinking just glue direct to inside of lens. May need result re-calibrating to compensate for IR loss by both RX & TX through lens.
