Hygrometer.. where to go?

I do not use a digital hygrometer, I use one of those ones that are small and still costs you like $10 more than you should really spend on it. I will get a digital hygrometer soon, just using this for now. In my 20 gallon, I hot glued the hygrometer to the very top of the middle of the enclosure because I had tape on in before but she knocked it down every single night. I don't think I put it in the right spot.. soo.. where should I put the hygrometer? Like right on top of the subtrate, in the middle of the glass in the tank, on the warm side of the tank, on the cool side of the tank.... you tell me lol. I have it in the middle of the enclosure, hot glued all the way at the top so it's pretty close to the heat lamp, though, the heat lamp is on the left side of the enclosure and the hygrometer is in the middle.

I use the Accurite and I just lean it up against the cool side hide. She moves it occassionally, but usually it's time to clean up some pee anyways. However, I ran the probe cord under the newsprint under the hide so she can't move it too much.

I don't use digital hydrometer either I just keep mine in the middle of my tank right above the substrate.

I put my thermometer and hydrometer in the middle just to measure ambient temps and relative humidity. I have a temp gun for measure hot spots and cool sides.

Place the new hygrometer right where the snake will be, close to the ground.
