Show HN: Enviro+ for Raspberry Pi – Environmental sensors

I wonder how easy it would be to convert, or design something similar to the Enviro+ that is in a waterproof enclosure with battery. Could be useful for collecting data on some basic water quality(turbidity,conductivity,pH,temp) alongside water level.

We currently use In-situ Aqua Trolls[1] to gather these parameters, but a solution like this could almost be considered disposable; hand them out to people in remote areas and you could potentially realise data for rivers/creeks that rarely flow, and would otherwise go unmonitored due to the time and finial investment required.

Very interesting project, thanks for sharing!

The trick with waterproofing is that it's easy to do rainproof enclosures, but much harder to make fully submersible things.

For measuring water parameters I would be tempted to use a rugged box for the Pi and then cable (via a removable connector) to something you put in the water. Basically design a probe like the device you linked. The fewer parts that need to be fully waterproof the eaiser life gets.

Absolutely! There have been too many attempts by management to push our technical team towards devices with replaceable batteries as a means of reducing operational expenditure. Such loggers fail, often.
