I have two different temp/humidity sensors sitting on my desk. One is an ESP32 with a DHT22 attached and the other is a Zigbee sensor like the one here in this picture.

iirc, a saturated table salt solution in a closed container filled with air will hit equilibrium at 75% relative humidity
so if you put both sensors into a warm lunch box with salt water (so much salt that it stays solid at the bottom) and wait a while, you'll see which of the sensors is bad. (of course make sure the sensors don't make direct contact with the salt water, using a bowl or whatever)

You can believe neither, they both will have inaccuracies as should be specified in their datasheet

Not like you're getting one of those with most Tuya-"branded" sensors
