Wireless sensors measure humidity, temperature and CO2

Paul Boughton
E+E Elektronik is introducing EE240 wireless sensors for the measurement of humidity, temperature or carbon dioxide (CO2). Up to three intelligent probes can be connected to each transmitter; each probe operates independently and can be hot-swapped. Remote probes allow the sensing head to be placed at a distance of up to 10m away from the transmitter. These features make the E+E wireless sensors especially suitable for industrial applications that require sensors to be routinely recalibrated without affecting network operation. The measured values can be read directly from the display on the transmitter or remotely using a web browser on any PC in the company's network.
The base station features a digital Ethernet interface for connection to the network and data analysis. The integrated web server enables users to configure the wireless sensor network easily and individually from any PC without installing any software. The base station comes with four analogue outputs for connection to a system controller.
A mobile measuring system with up to 500 transmitter stations can be built without having to install any wiring. In addition to this high degree of flexibility, coded bidirectional communication ensures completely secure data transmission.
E+E says its wireless sensors are sealed to IP65, which makes them suitable for use under demanding operating conditions as well as in outdoor applications.
Wireless routers are available to expand the network and range or to bypass obstacles.
