    S500 series RS485 Communication Real-Time Monitor System Solution


    S500-RS485 real time monitoring system based on RS485 comunication , data transfer using RS485 communication interface, which installation is simple and convenient, the technology is mature, system stable and economical . This system with a single temperature humidity recorder for acquisition, at the same time on a large area of a plurality of temperature and humidity monitoring points, monitoring and management of records, is the automatic monitoring system of a set of 24 hours of uninterrupted real-time monitoring.

    This system has powerful monitoring function, integrated all data to a PC server, system monitoring software for data storage and analysis, can print historical data and graphs. When the equipment data exceeds the upper limit or lower limit value, the system alarms in many ways: enternet sound and light alarm , GSM( SMS) alarm, email alarm ,ect. The instrument itself has the data storage function, support power resume, when the PC server monitoring software is closed, the external power supply failure, recorder by automatic battery data recorded in the instrument, when the PC server or external power supply return to normal, data stored in the instrument will be uploaded to the the PC server, to ensure data integrity.
