ORIA Thermometer Hygrometer, Bluetooth Humidity Temperature Sensor Mini with Data Export and Alert, Temp Humidity Monitor for House, 2 Pack

After looking through many humidity sensors I settled on these. Great price and highly accurate as I have done comparisons between their reading and my variety of Ambient, Logia and Acurite sensors and these are dead accurate. Small and easy to mount in places. Have one in my guitar case and another in my camera cupboard and just awesome to keep track of them via my phone. I emailed their support on a Saturday to ask a question about the app and wasn't expecting a reply until next week but got one within an hour. So far so good and ordered 4 more.

Buen producto alternativo a termómetros interno y externo o útil para verificar operación de equipos de refrigeración sin necesidad de disturbio en apertura de los mismos al conectarse en bluetooth.

Easy and checked with a sling psychrometer.

Uno de los sensores está descalabrado 2 x/100 y me tarde algo en encontrar la descalibracion tuve que comprar otro hidrometro para poder detectar la falla y hice varias pruebas para detectar cuál era el que estaba erróneo

Except for the strange battery choice this is a nice temperature and humidity logger. Unfortunately that's all it does there are no alerts for when specific temperature has been reached. The unit is not water resistant and when it gets wet it stops working.
