Cold chain temperature and humidity monitoring system

1Cold chain temperature and humidity monitoring systemSystem Introduction

Cold chain temperature and humidity monitoring system/The wireless temperature and humidity monitoring system (433M+GPRS+cloud service) consists of a wireless temperature and humidity collector (monitoring terminal), a wireless temperature and humidity receiving management host (receiver), cloud server software, and a mobile app. The system uses various transmission technologies (433M, GRRS) to easily network and monitor environmental temperature and humidity. The software has powerful and rich functions, making it easy for users to use. Check temperature and humidity data anytime, anywhere through a computer or mobile phone in a place with internet access.

3、 Introduction to System Functions

1. Real time collection and display function: The monitoring terminal collects real-time temperature and humidity values within the monitoring area and displays them directly on the LCD screen.

2. Wireless data transmission function: The monitoring terminal transmits data wirelessly to the wireless management host, which then transmits data from multiple monitoring terminals to the local computer or cloud server through various optional methods.

3. Alarm prompt function: In case of abnormal data, such as temperature and humidity exceeding the upper and lower limits, alarms can be output through different methods, such as sound and light alarms on monitoring terminals, SMS reminders on mobile phones, and monitoring software on mobile phones or cloud servers

Show.

4. Data storage function: The monitoring terminal and wireless management host come with built-in memory and use a first out method to store a certain amount of data. All data is saved on the local computer or cloud server, and temperature and humidity changes, as well as alarm information, are automatically saved according to scheduled settings. In the event of communication interruption, the monitoring terminal's data can be transmitted to the wireless management host, which can then transmit to the local computer or cloud server. The multi-level storage and transmission mechanism ensures data security.

5. Data statistical analysis function: The wireless temperature and humidity monitoring system displays real-time or historical changes in various parameter curves in the monitoring environment, a list of data for time periods, and the maximum and minimum values of time period parameters.

6. Data report output function: Based on the selected time period, output temperature and humidity reports in formats such as TXT, PDF, etc.

7. User grading management function: The wireless temperature and humidity monitoring system has strict password and user grading system, with different levels and permissions to ensure effective security of the system.

8. Multiple monitoring terminal and accessory selection functions: The wireless temperature and humidity monitoring system monitoring terminal can be configured with different types of probes as needed, such as single/dual channel temperature probes, temperature and humidity mixed probes, or ultra-low temperature probes. Multiple options to meet the needs of different usage scenarios.

9. Data query function anytime and anywhere: The wireless temperature and humidity monitoring system adopts cloud server technology, which can query current data, historical data, data reports, data curves, alarm records, etc. through WEB, mobile APP and other methods. Whether it is a mobile app or a cloud server monitoring software, the interface is beautiful, powerful, intuitive and easy to use, which can greatly improve work efficiency.
