Temperature monitoring accuracy up to±0.3℃The humidity monitoring accuracy has reached±2.5%RHIt can accurately measure the temperature and humidity values in various areas of the warehouse, providing accurate and detailed data support for management personnel. High data collection frequency, capable of automatically collecting temperature and humidity data at set time intervals, with a collection frequency not less than20Once every minute, ensure timely monitoring of the dynamic changes in temperature and humidity inside the warehouse. At the same time, it has a large capacity data storage function that can store at least30The temperature and humidity data of the day is convenient for management personnel to query and analyze historical data, providing a strong basis for evaluating and optimizing the storage environment of electronic components. In addition, it supports multiple communication methods such as Ethernet and wireless communication, enabling stable and reliable data transmission with upper computer software or monitoring platforms, realizing remote monitoring and management, and facilitating management personnel to grasp the temperature and humidity conditions of the warehouse anytime and anywhere.

（three）Infrared intrusion alarm quantity1Set up（1Taiwan)As the security guard of the warehouse, the detection range of the alarm should cover a radius of not less than110Mi can accurately monitor the entrance and important areas of the warehouse, effectively prevent personnel from entering, and ensure the safety of components in the warehouse. High detection sensitivity can accurately identify the movement of personnel or objects. Once abnormal intrusion behavior is detected, an alarm signal will be immediately issued to notify management personnel to take corresponding measures in a timely manner. At the same time, the alarm has the characteristics of strong anti-interference ability, which can avoid false alarms caused by environmental factors or misoperation, ensuring the accuracy and reliability of the alarm.

（four）BINumber of large screens displayed:1set1Taiwan.BIThe display screen is the information display center of the system, with high-definition and large-sized display characteristics, which can clearly and intuitively display important information such as temperature and humidity monitoring data, equipment operation status, etc. in the warehouse. Management personnel can view the real-time temperature and humidity trends in various areas of the warehouse, as well as the operating parameters of equipment, through a large screen, in order to promptly identify problems and make adjustments and optimizations. At the same time, the large screen also supports multiple data display methods, such as curve charts, bar charts, reports, etc., which facilitate data analysis and comparison for management personnel and provide scientific basis for decision-making.

（five）transmitter quantity1set1TaiwanThe transmitter plays a crucial role in signal conversion and transmission in the system. It can convert the weak electrical signals collected by temperature and humidity sensors into standard signals (such as4 - 20mACurrent signal or0 - 5VThe voltage signal facilitates subsequent data processing and transmission. The transmitter has the characteristics of high precision and high stability, with small conversion error, which can ensure the accurate transmission of thermal and humidity data and provide reliable guarantee for the precise control of the system.

（six）Intelligent centralized power supply quantity1setThe intelligent centralized power supply provides stable and reliable power supply for various devices in the system. It has intelligent management function, which can monitor the output voltage, current and other parameters of the power supply in real time, and intelligently adjust them according to the actual needs of the equipment, ensuring that each device can operate stably at the appropriate voltage and current. At the same time, the intelligent centralized power supply also has functions such as overload protection and short circuit protection. When abnormal situations occur, it can automatically cut off the power supply to protect equipment and personnel safety.
