Wireless Thermometer Hygrometer Refrigerator Freezer Monitoring System with Remote Access and Alerts via WiFi Gateway

1. The Bluetooth hygrometer can be used alone. The open distance is more than ten meters. The distance is greatly reduced when there is a block. The mobile phone does not need to be together with the hygrometer. The hygrometer can store data for 20 days when it records once a minute. The thermometer and hygrometer usually store data by itself. After it is connected to the Bluetooth of the mobile phone, it uploads the stored data to the mobile phone. The data can be viewed in the mobile phone, exported to Excel, and pdf can be sent to the computer using the mobile phone (the mobile phone does not need to be kept with the thermometer all the time).
 
2. If the Bluetooth to WIFI gateway networking is combined, 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 the temperature and humidity out of range alarm. One gateway can connect 10 thermometers. After connecting to wifi, data can be queried across provinces, across borders, across borders, and on mobile phones.
 
3. Generally, a gateway is required in a room. If 10 Bluetooth thermometers are in the same room, these 10 Bluetooth thermometers can share a gateway to connect to the router’s wifi.
