It works, but I the specs at [datasheethub](https://www.datasheethub.com/am2302-temperature-and-humidity-sensor/) seem kind of meh quality. I’m guessing an “accuracy” of 0.5C means it might be +/- 0.5C from reality. A “repeatability” of +/- 0.2 C I guess means precision of 0.2C Given the first two parameters, I’m not sure a “resolution or sensitivity” 0.1C matters. In any case, I think the number after the decimal is pretty meaningless in FLOAT temp; you might as well just round to the nearest integer if the accuracy of the measurement is 0.5C with a precision of 0.2C.

This thing has been collecting dust in my box o parts for 10+ years. Is there a better temp sensor in the $10 or below price range that I can hook up and use with mmbasic using just one GPIO pin?

If you want higher that 0.5c accuracy you might need to move to a platinum (pt100) sensor. Not seen any with 1-wire interface though but might exist.
