These work weii and within spec.

### ⭐⭐⭐⭐⭐ Plug and play
*by C***E on 30 September 2023*

Only used the analogue output but output to arduino and read the value. Simple 5v supply but seem to work ok on 3.3v too Calibration is still a work in progress

### ⭐⭐⭐⭐ Works just fine, soldering might do better
*by S***Y on 29 January 2025*

The soldering was a tad bit loose & needed constant adjusting to get any output from the sensor itself. But worked fine after a bit of fiddling around
