cheap network/ethernet thermometer

[sm_jamieson]

Mate of mine is looking for a cheap thermometer that can be connected directly to a network port to be monitored elsewhere (like IP cameras etc). USB connected would possibly be OK, but the nearest PC may be up to 10 metres away. There are some wireless weather stations that have a "base station" that connects to a PC, but that is not ideal. Most "network thermometers" around seems to be "pro" kit and quite expensive. Anyone got any ideas, for max 30 quid ? Cheers, Simon.

nanode + temperature sensor

1-Wire DS18B20 plus USB interface(*)? How do you want to access the temperature data over the network?

(*) Or perhaps a pin on the parallel printer port. Serial port would require a TTL to RS232 converter, that assuming the PC has either or both of those...
