This rugged high-performance and low power consumption OMEGA® ZW-ED wireless sensor/transmitter system provides web-based monitoring temperature, humidity, and barometric pressure.

The radio is an IEEE 802.15.4 compliant transmitter operating at 2.4 GHz designed to transmit up to 1000m* (3280”) outdoor and around 100m* (328”) indoor to a ZW-REC coordinator. The ZW-REC connects directly to an Ethernet network to serve active web pages and display the data. You can monitor and record temperature, relative humidity, and barometric pressure over an Ethernet network with no special software—just your web browser.

These wireless devices are designed for demanding industrial applications indoors and harsh outdoor environments. The electronics are protected in a rugged weatherproof polycarbonate NEMA 4 (IP65) rated housing. A variety of compatible probes are available to suit your application.
