Environmental monitoring system
This environmental monitoring system consist of 3 parts: the device layer , control layer and user layer.
User layer : including any authorized computers in this system. These devices is allowed to access thereal-time running information and historic data of this system after installed the ToClient software. Working principle: all data is stored in the database of control layer(control server). Users can view the real-time/stored data via LAN/Internet.
When the monitoring data value exceeds settings set by user, this software will also play alarm sound or send email/SMS to alarm users.
Control layer: the ToMonitor runs on a server, it writes all real-time data collecting form end devices to SQL
database, it triggers the alarm function when data value exceeds settings.
Device layer: all the high precision loggers records temperature, humidity and other data automatically, then sends the data to ToMonitor for processing. With battery, our loggers continually records data when the server is shutdown or there’s line faults, so the data will not be lost .
The device layer includes temperature & humidity data logger and wireless repeater, the function of this layer is to collect, record and upload temperature & humidity data . The data logger collects and records temperature & humidity data from surrounding environment and upload it to a server via wireless repeater.
ToMonitor is server software, it stores data uploaded from data loggers and displays it on the software. Users can set temperature and humidity value range for each devices, when the value exceeds limits, the software will alarm user immediately.
ToClient is the client, user can access server via this software to view real-time/recorded data of each temperature & humidity data logger.
