S500 series WiFi Real-Time Monitor System Solution


The working principle of S500 WiFi series temperature humidity data logger, as long as there is a WiFi can work and have a device can access the internet( mobile phone, tablet PC or personal computer), user can begin to to test and monitor temperature and humidity. No matter where you are, as long as there is WiFi, user can control at anytime. It is sensor imported from Switzerland or America,with high accuracy and stability.

In this network, there are many monitoring station. Taking into account the problems of wireless signal and reliability of the network, we use hybrid network Ethernet and wireless devices. ToMonitor software uses TCP/IP network protocol to monitor each base station. The base station is used to collect data for each network, and then sent via Ethernet in real-time to ToMonitor system host. Network mode uses client/host framework and the principles of centralized monitoring of the distribution of the base station , so that there is no interaction between the single point of failure. At the same time, test independent measurement and control principles greatly improves the system reliability.
