Although it's very cheap, it works great. Now I want to have motion detection outside. Does anyone has some suggestions to wheater seal the sensor? Can I put it in a box? Cover it with Sugru?
i m in germany and use the cheapest slime i can find...
i just take care that it is good for fish tanks... when it doesnt hurt fishes then it wont hurt me...
Use a conformal coating, this is used for Marine electronics and "permanent" connectors. The PIR "lens" is probably OK outside, unless the device is in the baking sun all the time, however the external circuit and connections can collect humidity and therefore corrode, so the conformal coating is pretty effective against that.
I have found that silicone can affect sensitive circuits (due to capacitance?).
