Newport Electronics' zSeries wireless sensor system provides web-based monitoring of temperature, humidity and barometric pressure in critical applications. The compact wireless "end devices" mount discretely on the wall in clean rooms, laboratories and any remote facility. End devices transmit up to 300 ft. (without obstructions) to a "coordinator" connected directly to an Ethernet network and the Internet. The wireless system complies with IEEE 802.15.4 operating at 2.4GHz.
