Wireless sensors for humidity, temperature and CO2 measurement
EDN Europe, 08 Sep 2010
EE240 wireless sensors from E+E Elektronik are the suitable solution for high quality wireless measurement of humidity, temperature or 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 wireless sensors suited for industrial applications that require sensors to be routinely recalibrated without affecting network operation. The measured values can be read directly off the display on the transmitter or read remotely using a web browser from any PC in the company network. The base station features a digital Ethernet interface for effective connection to the network and data analysis. The integrated web server allows you to easily and individually configure the wireless sensor network from any PC without installing any software. The base station comes with four analogue outputs for connection to the system controller. A mobile measuring system with up to 500 transmitter stations can be built without having to install any wiring. In addition, coded bidirectional communication ensures secure data transmission. The wireless sensors conform to protection class IP65, making them suitable for use under demanding operating conditions as well as in outdoor applications.
