## Description

desertcart.com: ThermoPro TP55 Digital Indoor Hygrometer Thermometer, 4-Inch Temperature / Humidity Monitor with Touchscreen and Backlit, Indoor Room Thermometer / Humidity Meter for House Home Greenhouse : Patio, Lawn & Garden

Review: Great unit at a reasonable price!! - This unit was smaller than I expected it to be, but actually it’s plenty large enough for its purpose. Digits are easy to read. I installed the sensor outside underneath my deck, on one of the upper boards. Then I put the display unit in my kitchen, only about 12-15 feet away. At first I placed the display unit on my fridge using the magnetic backing, but when I did that the display disappeared. It says somewhere in the manual that putting it on a metal surface with the magnets may cause it to have problems receiving the signal from the sensor. So a no-go on that. I put it on my counter top and it receives just fine. The external sensor I just hung on a nail. VERY easy install!!! Hahahaha I like how this unit gives a readout of temp and humidity for indoors and outdoors, and also a “trend line” for each - is it rising, falling, or remaining fairly steady? That’s nice. Also, the readout on mine seems to be pretty accurate. Be aware that when you first install it, it will take some time (maybe 30 to 60 minutes) for the display to give accurate readings indoors. Takes times for the sensor to adjust, I guess. Ever since that initial period it’s been spot-on. Before looking these up on desertcart, I had no idea that these things even existed!! That is, external sensor sending wireless data to internal display unit. That is so cool!!! And amazingly inexpensive too. I’m so impressed, that after I do a residential move in the next year, I plan to get one of the higher-end weather stations, that does it all - temp, humidity, barometer, wind speed, rainfall amounts, etc. THAT will really be cool!!! But for now, this little device works just find for my needs.
Review: Great thermometer. Easy to read. - Gives a lot of information for the price. Easy to read even without the light. I have a family room that has a wood stove for the heat. I want to know the temperature of the room so i don't get it too hot and waste wood which is expensive. So I put the thermometer in that room and determine the temperature of when I should start the stove and how much wood I need to add maintain the temperature I want. Works great for that.

## Questions & Answers

**Q: I didn't see calibration mentioned in the instructions and there's no calibrate button, is the humidity sensor fairly accurate?**
A: Cannot be calibrated.  I bought this and 2 cheaper adjustable AcuRite units.  In addition, I have an older ThermoPro indoor/outdoor and two Honeywell smart thermostats that are supposed to be able to control a Honeywell dehumidifier.  Six readings ranging from 38% on the indoor/outdoor for it's indoor reading; THIS ThermoPro and one of the AcuRites at 43%, the other AcuRite at 42%, and the Honeywell thermostats at 44% and 45% (although they're on different floors--the 44% was nearer my three new units).  So, six opinions from 38% to 44% (ignoring the Honeywell on the other floor), with two at 43%.

**Q: Does the backlight stay on constantly or does it shut off and u can turn it on if you need?**
A: When you press the lightbulb icon it activates the backlight and will automatically shut off in around 15 seconds giving a time to view the display, or if you press the lightbulb icon again before the 15 seconds it will shut off when you press it. There is no way to keep the backlight on or extend it beyond 15 seconds except to press the backlight icon after it shuts off, and cannot press it again to extend time before that or it will turn off.

**Q: How long do the batteries last under normal usage?**
A: I purchased this on January 26th, 2019 so Ive had it a year and 2 months and the battery gauge reads on the lower end but it still works!

**Q: Will sitting this on a window ledge above the kitchen sink result in inaccurate readings?**
A: Sitting on a window ledge above the kitchen sink will not give you accurate readings for the ROOM.
The window will affect temperature readings and if you are running hot water in the sink, the humidity readings will probably go up.
