Digital Thermometer with BS2 Good price!!!

NWCCTV

I just came across these on EBay when I was looking up the L297's @erco mentioned in another thread. Seems like a good price as DigiKey sells for $4.67 each. Any how, I am wondering how easy it would be to wire up to a BS2 or Prop?

At 10 for $9.99 and free shipping (~2 weeks) the price is not bad at all. Per the datasheet this device outputs temperature in Celsius, a signed, 2's compliment word using 1-Wire interface. Don't know about the Prop, but only the BS2P series supports 1-Wire. You would have to bit-bang the BS2.

Good price IF you need 10 and they work in your application. There are counterfeit and at least two different legit versions: http://www.picaxeforum.co.uk/showthread.php?22383-DS18B20-only-read-85/page2&highlight=DS18B20+parasitic
