1. Overview of the program
The temperature and humidity monitoring and early warning system of LoRa wireless technology uses LoRa collector and LoRa gateway to achieve full coverage in the monitoring area, and at the same time, temperature and humidity sensors are installed in each data collection node in the storage area to realize the dynamic full collection of temperature and humidity data in the monitoring area, and monitor, collect, transmit and warn the temperature and humidity data according to the actual needs of the storage environment. After the data is transmitted to the platform, data analysis and optimization are carried out, and then it is pushed to the web service system or mobile app to achieve real-time monitoring, scheduling control, etc. In order to maintain the quality of stored goods and create a suitable storage environment, it is necessary to monitor the temperature and humidity information of the environment in real time, and once the temperature and humidity are abnormal, it is necessary to adjust and control them in time, so as to ensure stable quality and avoid losses. It provides an industrial Internet of Things solution integrating software and hardware, based on the needs of temperature and humidity monitoring and early warning, to create a LoRa wireless data transmission system to realize the best monitoring of the storage environment 7*24 hours a day, and is widely used in logistics warehouses, museums, laboratories and other scenarios.
IISystem introduction
The temperature and humidity monitoring and early warning solution of LoRa gateway wireless data transmission uses LoRa gateway base station to carry out full coverage of wireless signals in the monitoring area, and at the same time, LoRa modules are installed in each data collection node in the storage area to realize the dynamic full collection of temperature and humidity data in the monitoring area, and monitor, collect, transmit and warn relevant information in real time according to the actual needs of the storage environment. After the information is transmitted to the system management platform, the data system is analyzed and optimized, and then accurately transmitted to the WEP service system or mobile APP system to achieve real-time monitoring, regulation and management, and ensure that the monitoring area environment is suitable.
The sensor cloud is based on the Internet of Things technology, which does not require any software system to be installed on the user side, and after the sensor is configured, the data can be accessed and read by using the Internet computer; When the sensor exceeds the set threshold, the mobile app will push an alarm message to you so that you can take measures in time. Data is stored in Alibaba Cloud and automatically backed up on a regular basis. User data permissions are managed by themselves to ensure data security; You can also use the Internet to access the cloud system anytime and anywhere, view data, and export Excel data reports.
IIISystem features

In the future, with the continuous development of LoRa technology, LoRa real-time temperature and humidity monitoring solution will be applied and promoted in more fields.
Sixth, the field of application
Hospitals, disease control laboratories.
With wireless temperature and humidity sensors, you can monitor the ambient temperature and humidity of your laboratory anytime, anywhere.
Sensors are placed in the refrigerator to monitor the storage temperature of the drug and prevent the drug from becoming ineffective due to power outages or refrigerator malfunctions.
After the large supermarket island cabinet is equipped with a temperature sensor, there is no longer a need to manually register each refrigerator display case every 2 hours. Through the cloud platform, managers can use their mobile phones to check the temperature of each refrigerator, deal with alarms immediately, and export reports at one time at the end of the month. In order to safely monitor the temperature of refrigeration and freezing equipment, large supermarkets often use traditional methods to collect and record data manually or electronically. The disadvantage of this approach is that there is no automatic alert to the person in charge when the temperature exceeds the limit or when the refrigeration function is actually disturbed. Monitor in the Sensor Cloud** to view, manage, and analyze data anytime, anywhere from a PC, smartphone, or tablet. If the threshold is exceeded, the system will automatically send an alarm.
The temperature of the warehouse of the natural history museum should be basically constant at about 20, the temperature difference should not exceed 7C, and the relative humidity should be kept at about 50%RH. When the temperature and humidity in the warehouse are not suitable for the storage of goods, effective measures should be taken to adjust the temperature and humidity in the warehouse in time. The temperature and humidity sensing monitoring system using LoRa wireless communication technology can realize automatic monitoring of temperature, improve safety and work efficiency, and most importantly, there will be no hidden danger of temperature exceeding the threshold, and the alarm information will be received as soon as there is a device failure.
