DS1631 / DS1621 I2C temperature sensors 

===== Temperature =====

==== IC (chip) sensors ====

|  TO-92  | Analog temperature sensor  \\ -40 C - 125 C |  [[http://www.analog.com/en/sensors/digital-temperature-sensors/tmp36/products/product.html|TMP36]]  | [[http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=TMP36GT9Z-ND|Digikey]] |

==== RTD ====
Platinum wire resistive sensors

=== Class A ===
±0.03 to ±0.15 °C accuracy

  * [[http://www.k-instruments.co.uk/acatalog/PICO_.html|K instruments]] (also sold at [[http://www.picotech.com/pt100_sensors.html|Pico tech]]) Pt100 probes for air, immersion 
  * [[http://us.fluke.com/usen/Products/ProductModelStockCheck.htm?pid=1031&cs_id=35633%28FlukeProducts%29&category=|Fluke FP-Plus probe]] used for [[http://us.fluke.com/usen/Products/Food+Pro.htm?trck=foodpro|Fluke's food-temp measuring meter]] (how convenient!) Pt1000 (1000Ω at 0°C) Bit squat but surely adaptable

=== Class B ===

  * [[http://www.omega.com/ppt/pptsc.asp?ref=PRTF-10|Omega PRTF-10]] General purpose class B ±0.3 °C accuracy

== Radioactivity ==

**Geiger Mueller Tubes** - Handy for people looking to make random number generators or detect radiation. Tubes tend to be Cold War old stock from Russia/US, and tend to be used for detecting Gamma and Beta radiation. You'll need a high voltage boost supply - check nixie tube projects for some HV supply designs
