Probe placement

[DandD]

Setting up a new cage. Where is the best place to put my temp probe on the warm side? There will be heating pad under the cage on that side. Do I place the probe on the bottom of the cage there and just cover it with substrate? Willit hurt if the snake lays on the probe?
On the cool side I will have a RHP. The probe on that side maybe on the side of the cage about an inch from the bottom?
Thank for any help!!

the probe for your uth always goes between the uth and the bottom of your enclosure. Not on the inside of your enclosure.
