This is what you're looking for
For so long I've been looking for a meter with a remote sensor that reads humidity well temperature *both indoor and outdoor,* and this does so extremely well. Range is impressive and consistent. Easy to set up program. I did have to take out and replace batteries a few times before the meter synched the sensor, but once it was going it was great. Tested the accuracy against three different tried and true temp monitors, and it's extremely accurate, often with a few tenths of a degree +- , and one or two percentage points for humidity. Wish the display was backlit, the sensor has a flashing red light that has to be covered with tape, but those are the only complaints.
