Default Water Temp Sensor?

Does anybody know of a bluetooth remote water temp sensor that I could mount on my dock and check the water temp on my phone?

You might check with Lacrosse to see if they have a marine seawater compatible temp sensor but that may be a pretty long-shot.

Here is a WiFi version

http://www.monnit.com/Product/MNS-2-WF-TS-WT-L03

It comes in several different variants

For the two last an Ethernet or USB gateway is needed

it's too bad these liquid temp sensor probe cables only seem to be available in 3' lengths or less since that makes safe installation of the sending device not very good for use in tidal areas and/or where waves build up .

TTaxi, thought the same thing. Thinking of mounting on a pole(think floating dock type poles that allow the dock to move up and down with the tides) so it can "float" with the water changes. Probe always remains in the water, but the sensor will sit above the water level by a couple of feet(assuming I put the probe a foot under the water).

According to the spec sheet, the device itself is intended for indoor use only and is not weather proof.

So, would have to be mounted in something like a waterproof dock box. Ask them if the sensor cable can be spliced, or ordered with a much longer cable.

An alternative would be a floating pool/spa remote thermometer, wireless, but not WiFi, uses its own indoor display...most of these devices operate on the 433mHz band, like garage openers, car keyless remotes, etc.

That particular one only has a transmit range of 100', but others on the market claim 300' range.

The LilyPad, by Poolsmart, is WiFi, but distribution in the US seems to be on hold...it's a Swiss company.
AMZN previously listed it, but now shows the product as unavailable, yet the free phone app continues to be downloadable.

How difficult would it be to trench and run cable to the house? That would expand your choices, since there are even temp. probes available for multimeters.

Also, you may be able to find a web site that shows current water temp. for your particular body of water, the cheapest solution. I'm on a 130-mile long lake, and there are several gaging stations with websites...surface water temp. is nearly the same everywhere on the lake, but we have thermoclines that can cause a 30° variation with depth, which varies tremendously on location.

The third product I linked to has IP65 specification so it's intended for outdoor use.

there are a few wireless fish finders designed for ice fishing that transmit to your smart phone. They are full sonar units but they offer water temp too. there are plenty on the market but here are a few
