Hot Tub or Pool Arduino Temperature Monitor

If you wish to monitor only the temperature of your spa or swimming pool, this Arduino project (OpenSpaMonitor) can be easily adapted for this and would be quite inexpensive.   The estimated price for this would be around $70 US.   Another option that I just found on the site is a wireless temperature only node kit.  The emonTX low power temperature node kit is only $30 US, in addition you would need a waterproof DS18B20 temperature sensor.  Pair it with the Nanode RF and you could easily make a wireless hot tub temperature sensor that displays on your Android or iPhone.  Add triggers to your Cosm account for a freeze alert for your spa.
