WiFi Gateway Temperature/Humidity/Dewpoint/VPD Thermometer/Hygrometer Monitor Refrigerator Freezer Fridge Alarm Alerts

1. The Bluetooth hygrometer can be used alone, with an open distance of more than ten meters. When there is an obstruction, the distance is greatly reduced. The mobile phone does not need to be with the hygrometer. The hygrometer records once a minute and can save 20 days of data. The thermometer usually saves data by itself. After connecting to the mobile phone Bluetooth, the saved data is uploaded to the mobile phone. The mobile phone can view the data and export it to Excel. PDF can be sent to the computer by mobile phone (the mobile phone does not need to be with the thermometer all the time).

2. If the Bluetooth to WIFI gateway is networked, multiple mobile phones and computers can remotely query the temperature and humidity, remotely view the historical curve, and multiple mobile phones and computers can remotely receive temperature and humidity out-of-range alarms. One gateway can connect to 10 thermometers and hygrometers. After connecting to wifi, you can query data across provinces, countries, and borders, and mobile phones.

3. Generally, one room requires a gateway. If 10 Bluetooth thermometers are in the same room, these 10 Bluetooth thermometers can share a gateway and connect to the router's wifi.
