[edit] Temperature

• Some microcontrollers, such as the Atmel ATtiny, include an internal temperature sensor accurate to +-10 Celcius)

• "1-wire" temperature sensor accurate to +-0.5 Celcius
  • software to make nice graphs from a bunch of temperature sensors on a "1-wire network"
  • nice waterproof packaging
  • pretty pictures of the actual sensor (plus wires and connectors)
