Indoor Hygrometer Thermometer 3 Pack, Bluetooth Humidity Temperature Gauge with Large LCD Display, Notification Alert with Max Min Records, 2 Years Data Storage Export for Room Greenhouse, Black

Accurate readings. Easy for digital data transfer.

Excelente produto! Sensor bem preciso, e boa qualidade de construção. Fiquei positivamente impressionada com a facilidade de uso do aplicativo e visualização dos dados. O equipamento armazena dados durante algum tempo (eu ainda não testei quanto tempo - mas pelo meu uso, pelo menos 24 horas), e depois os dados são facilmente baixados por bluetooth para o celular ou tablet, em forma de diversos tipos de visualização de gráficos. Recomendo bastante o produto!

The 3-pack set of hygrometers was purchased to verify the calibration of smart thermostats that were part of a newly installed A/C system. Setup for the devices was easy and the app is easy to use. As near as I am able to determine the devices are pretty accurate (measured against the A/C installer's professional temperature probe). The price was good, however, they were smaller than I expected and wireless would have been preferrable to bluetooth as the the units do occasionally disconnect due to bluetooth distance limitations.

I love these for monitoring the temperature and humidity in my reptile cages. I just set them in the substrate or attach to the sides with mini Velcro strips. They give clear, accurate readings and the app works well. I only wish I could track them while not at home, but no complaints otherwise.

These thermometers just work the way they are supposed. No matter what batch you get, as I have bought them several times, they are all in spec and compared side be side neither temp or humidity vary by more than one number, in many cased they show same,So an outstanding value for the price not even considering the remote history download and super easy pairing with their phone app

Perfect after 1 month of useDelivered on time July 5th. I ran the the units side by side to compare readings for several hours a after which they read the same temperature and humidity within +/- 1%. This was better accuracy than I expected or needed. After 1 month of use, flawless performance and battery still shows full for all 3 in app. App worrks well, but I didn't need the graphing ability so haven't checked that.Today I placed an order for 3 more to cover additional bedrooms and the media room.I hardly ever write reviews, but this worked better than other reviewed suggested it might, hence this review.
