thelassa "The battery lasts between 1 and two months." I think thats what he meant.
I might buy one and test it.

Okay well that wins the affordability factor haha! That may actually be worth a try. In fairness does it need to be any more complicated than that possibly not? If the one star rating isn't an indicator of quality I don't no what is.

Where is the SIM slot? Why does it say it works to 433Mhz... I don't think this is the whole thing...

Yeh the problem with that device is it runs off a standard battery - meaning you'd need more to get it running of 12v if you wanted it to last for a considerable amount of time.
I don't - go on ?

You could pop a 1.5V buck convertor in to power it. But beware the flat battery causing the bilge to flood...

Got one of these. Works well, but battery life (12V 23a) is two months top in actual practice.

Tell us more... with a SIM card in it?

So I'd go with one of these:

Red and Black as per convention.
Orange to a float switch with the other side to 12V.
when armed it should send a SMS if the orange goes to 12V

Hello all !

There's been a few times where I've wondered why I hadn't stumbled on a bilge alarm that sends a SMS message to your phone if your boats taking on water. I decided to have a research and see what's out there.

Here are the results!

£619.00 – Boatguard
£481.85 – BoatWarden Boat Alarm System
£363.61 – 20240-CA High Water Alarm
£159 – GSM-235 Marine Alarm
£120 – GSM PagerZ6 GSM Auto dialer
£99 – GSM 021
£57 – A5 GSM Alarm Auto-Dialer and SMS Sender

I've contacted the cheapest maker of GSM devices I could find and got them to write a tutorial about how you could use a float switch to trigger SMS messages.
Read my blog post about it http://www.boat-renovation.com/cellphone-bilge-alarm/

If anyone knows of any cheaper ways or methods- get in touch!

Let me add to that list. Skipper's Mate http://www.skippersmate.co.uk - free software. Uses low-powered cheap hardware. Does the bilge alarm and a whole lot more besides.

I think it broadcasts to any phone located within 30 metres of the device - so not much use for a bilge water sensor unless your boat is moored VERY close to your home.

Hmm- what about this @£3? 8 month battery life, remove reed switch with terminals for level sensor.

That is similar to what I set-up a few years ago, rewired/configured the wireless transmitter directly to 12volts (instead of using 12v battery) and also to the built in bilge alarm/buzzer, which connects to my GSM security camera/alarm (Alertpal) on the boat. So basically if the float switch is triggered by water in the bilge, the bilge alarm sounds and at the same time transmits to my GSM alarm and hence a text is received. Been using those wireless devices for years on boat and home and so far reliable. I have some pictures somewhere with some more details, I'll see if I can find them.

You could add a float switch to this gizmo and it will SMS you if it's activated.
Other functions include alarm activation, battery voltage alarm, temperature alarm and GPS position (if it moves out of area, you get a text). You can also switch things on remotely via SMS

Its worth digging them out- I'd love to take a look.
