Good but Needs Calibration
Does the job for basic humidity detection. You need to calibrate it against a known source for accurate readings, but for the price, it is excellent.

Perfect Module for Smart Home
Using this for my bathroom ventilation automation. It triggers the fan when humidity gets too high. Very satisfied with performance.

Works Great with ESP32
Easy to integrate with my ESP32 project. The analog output is stable and the digital threshold is adjustable via the potentiometer.
