Wireless Data Acquisition
Introducing WiSI ("Why-Sigh"). WiSI is an all-in-one radio, IP-67 rated outdoor/weather-proof data acquisition and control device designed for rapid deployment to monitor and control remote sensors.
WiSI feature model has an integrated solar panel, 10-year maintenance-free energy storage and communicates up to a week without sunlight. With a 2.4GHz radio, data is passed up to 2 miles per hop with 128-bit AES encryption.
Standard I/O includes 4 each: analog inputs, digital inputs, digital outputs; 5V and 18VDC instrument supplies for powering sensors or a 4-20mA loop, and an RS232 port. WiSI wireless networks integrate into systems via Modbus RTU.
