Humidity sensor problem

Anyone has any idea what might be wrong as I have 2 humidity sensors in about same place in my grow tent, but other shows 52% and other 38%. They are both from Spider Farmer, other came with grow tent and other from humidifier that I recently bought. So one of them has to be wrong, because sensors are so close to each other.

Probably both of them are wrong, tbh. Welcome to the world of cheap humidity sensors, and, to a lessor degree, microclimates in your grow.

you can buy 3 more and they’ll all read different. Will say though, that a 14% difference is pretty high, but anything under a 10% difference is pretty standard unfortunately. Pick one and run with it, or do mental math and average them. We adapt and adjust. Good luck.
