The Z Series Wireless system provides web based monitoring of real-time readings and charts of temperature, humidity, and barometric pressure, as well as thermocouples and any transducer with analog voltage or current output. The “end devices” transmit to a “coordinator” which is connected directly to an Ethernet network and the Internet. The coordinator is an independent node on the network sending and receiving data in standard TCP/IP packets. They are easily configured from a web browser and can be password-protected. You can also log data in standard data formats for use in a spreadsheet or data acquisition programs. The end device can trigger an alarm If variables, go above or below a set point. The alarm can be sent by email to a single user or to a distribution list, including text messages to cell phones. A number of completely Wireless end devices are powered by two AA or two C-cell alkaline batteries. These end devices can operate for weeks, months, or years before changing the batteries. High-accuracy web-based measurement of temperature and humidity monitor up to 32 Wireless sensors user-friendly, simple to configure alarms by e-mail or text message no special software required.
