Good accuracy, slow sampling
Data is accurate compared to my thermostat. Just remember it only updates every 2 seconds.

Needed pull-up resistor
Worked after I added an external pull-up resistor. Instructions could be clearer on that point.

Great value module
The shield board makes wiring much easier than the raw sensor. Highly recommend for beginners.
