Ideal as a basic temperature indicator - I use them on embedded projects to allow the system to monitor its own temperature so absolute accuracy is not a problem. Repeatability is more important and that seems fine. The 10 I bought were the G grade accord
These sensors are cheap, easy to use and give accurate feedback. They're fine on the Arduino, but they can't be used on the Raspberry Pi without adding a MCP3008 (or equivalent) analogue-to-digital convertor.
