After some research I decided to use this thermometer to monitor the CNC body, mainly for temperature control. The alarm clock was an added bonus and I love that I have another option besides the red LED to try to alert me. I did a test and it worked as advertised. Since it's in a non-air conditioned garage, it's nice to know the humidity and get a low temperature warning. So far everything has been within a degree or % of my other sensors. Very satisfied and better than expected!
