Veden lämpö

Kestääkö pro anturi upottamista järveen n.1m syvyyteen kesäksi veden lämmön mittaamiseen.

Google translates as:
Does the pro sensor withstand immersion in a lake to a depth of approx. 1m in summer to measure the heat of the water.

The radio waves will most likely not be able to reach through 1m. (even without waves in the lake :slight_smile: )
Ruuvi sensors floating on the water, even non-pro, can work for long periods but you need to cover the “breather” port with GOOD quality electrical tape.
