MLX90614 Modification - Weatherproofing!
I'm trying desperately to create a weatherproofed IR module and it's really causing me some difficulty. A truly IR transmissive optical sheet is hundreds of dollars for a tiny piece.
I've gotten my hands on a few MLX90614 thermometers (the actual piece from Melexis) and it turns out they are completely sealed and weatherproof, and have been mounted outdoors by some users. The problem is that they are insanely hard to operate with a Stamp2 or other microcontroller (as far as I can tell). I also have several of the Parallax sensor that incorporates the MLX90614 series and obviously. . .those work perfectly!
Question: It it possible to weatherproof one of the parallax sensors? I have both a 90 and 10 degree unit and even if I seal the lens on the 90, it would fill up with water in the rain. The 10 degree unit has the MLX90614 sensor mounted in such a way that it's physically impossible to protrude the sensor through an enclosure. I tried to remove the MLC90614 from one unit, but it was darn near impossible and I broke one that way.
Any help/recommendations would be much appreciated. Thanks!

Pin 2 SDA -> Prop Pin (29 works), needs 4.7K pullup to 3.3V
Pin 3 Vdd -> Prop Pin MLXPowerPin (16) - used to power the sensor, means the prop can power it down when there is a problem
Pin 4 Vss -> Gnd
So if up to now you tried communicating using PWM, it's normal that the MLX90614 did not respond.
I hacked it out of a $9 IR thermometer I got at Harbor Freight so my suspicion now is that it's not a normal MLX90615, maybe it's a specialized version that only does PWM. . .??? I just don't know how I would even tell quite honestly. I guess I need to bite the bullet and buy an oscilloscope!
