I'm after some inexpensive wireless temp+humidity sensors that can be
interfaced with linux *easily*.

No time for soldering - but I will do the programming.

Best I've found to date are the Arexx system:

http://www.conrad-electronic.co.uk/c...roduct/100788/

Combined with an Arexx BS-1000 LAN base.

The BS-1000 is a fair price, but the sensors are rather expensive
(need/want
5).

The next best idea was a TFA Dorstmann weather station where the sensors
are
£20.

http://www.amazon.co.uk/w/dp/B001K2QOB6/

That can be jacked in via USB to a computer.



Just wondered if there were any others?
Open wireless protocol like z-wave would be cool.

Cheers,

Tim

There's some beekeepers who have been testing such a system to measure
info inside the hives.

Just general monitoring around the house - including shed and roof spaces
(hence the interest in humidity).

You can get external temperature/humidity probes for APC UPSes, don't
know how cheap they are to purchase individually, or whether they could
be re-purposed?

Plugging together rather than soldering, but Arduino, DHT11 sensors and z-wave/zigbee/wifi modules?

That's rather interesting - I can program ATMegas too

The DHT11 says "0-50C" - is that actually true or is it because the humidity
sensor won't work below 0C?

DHT11 fixated , just got couple in post.

Marginally more expensive DHT22 goes down to -40C

Thank you - that will be researched
