I love these little devices. I use them from the bathrooms to monitor humidity to fridges to ensure they are maintaining temp. I've also had good luck using them to validate things like thermostats on our AC units are calibrated appropriately. My only suggestion is to find a way to validate and calibrate the sensors when you first get them. I find a cheap alcohol thermometer is good enough to make sure you are in the right area (this is more important for relative humidity as it is highly dependent on accurate temps)
