Adding a metal piece to improve the rate of water temp measurement reading

Ruuvi products 🇬🇧 RuuviTag & RuuviTag Pro sensors

Hey Ruuvi community, loving my Ruuvi Tag Pro for cold water dips.

Has anyone experimented with drilling a hole in the Pro tag and gluing with epoxy a stainless steel piece over the temperature sensor to improve the time to get to an accurate water temperature?

As a complete newbie to waterproofing electronics, interested in how to approach this the best way possible! Thanks yall!

Ruuvi seems to be the only piece of hardware out there to match my needs for this, just that the rate of getting an accurate water temperature is too slow!

Hello @etreimanis ,

Thank you for your message. RuuviTag, as any other sensor, shows correct measurements after a specific time called step time. You can read more about this here:

We don’t recommend using RuuviTag in water, as it’s not designed to work under water or to get in direct contact with water.

Hey @Marko ,

Many thanks and appreciate that you responded so quickly!
Thanks for sharing this blog post, super insightful!

  • Yeah understand that this is not the intended use and not optimal as BLE is close to impossible to read whilst Tag is under water.

I saw this blog post from 2022, that got me interested in using the 2in1 Pro model for my Ice Bath. https://ruuvi.com/catch-more-fish-with-a-fishing-thermometer/?srsltid=AfmBOoqiJeqZeMZS39uDLNWCnpELmTsPXnjNs9ULVtB6l9jaH4pNz3GO

Wondering if I will only waste my time trying to reduce the step time modifying my 2in1 Ruuvi Pro or should I just make an external TMP117 probe of my own then? Thanks again!

Hello @etreimanis ,

We have a RuuviTag Pro + external TMP117 temperature sensor package coming soon, but this is also not designed to be placed under water.

I added a 12awg copper wire through the cover with end “pressing” against the BME280.
