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.

Okay for the Price
Not high precision suitable for scientific use, but okay for hobbyist projects. The range is a bit limited at extreme ends.
Q: Is this module compatible with 3.3V logic levels?
A: Yes, the module operates between 3.3V and 5V DC, making it compatible with most microcontrollers.
Q: Does it provide an analog output pin?
A: Yes, it provides both analog voltage output and digital switch output via the comparator.
Q: What is the expected lifespan of the sensing element?
A: Under normal operating conditions, the sensing element has a long operational life, typically several years.
Q: Are there any specific Arduino libraries required?
A: No specific library is needed. You can read the analog value using the standard analogRead() function.
Q: Is the sensor probe waterproof?
A: No, the sensing element is not waterproof. Please protect it from direct water contact or condensation.
