I don't know of any sensors directly. You may need to use something like NetBiter hooked to your sensor of choice.

Well, here's one.

The spec sheet mentions ".Equipped with independent battery power supply GPRS signaling
unit," but is conveniently vague about what combination of power supplies: 3.6V Lithium, or battery + 220Vac, or Battery + 24Vdc powers the meter and the communications.

There is a claim of 3 year battery life, but my-school-of-hard-knocks experience is that any battery powered wireless vendor is off by some factor 2 to 10 for battery life claims.

I do have to say that I've encountered 3 situations of Chinese instruments that came with negligible documentation and there's no way to help someone who bought the low cost box without checking to see how they were going to work with it once it was in their hands. Caveat Emptor>

Note that it uses a proprietary IR handheld for configuration. Don't want to lose that puppy.

I saw a British one a bout 18 months ago that claimed a 10 year battery for a magmeter only, no radio comm, but I didn't save it and can't find it.

thanks guys...
