Not entirely related to pimatic …
I want to build a underwater temperature sensor with a ESP sending it to pimatic. There are a few problems on the road to be taken:
- Waterproof IP68
- How far can wifi reach underwater ?
- Battery lifetime
First things first, I need to test with a simple enclosure if wifi would work underwater. For my specific situation rang isn’ta issue. I have a AP hanging a few meters from the site I want to go underwater.
If wifi seems to work underwater it is time to find a cheap housing. Looking at ebay I think the cheapest way to go is using a GoPro or phone case with IP68 rating.
Next step : battery life. I think we can get a long runtime when only measring every 10 minutes and goto deep sleep after sending. It’s no problem that the ESP goes to very deep sleep without being able to contact or do stuff.
Any ideas? Does anyone has experience with such a project ? I won’t take no for an answer, if wifi isn’t possible I want to find it out myself
