Low cost temperature, humidity and light websensor with additional external 0-18V sensing input
The Websensor is an environmental monitoring device designed for remotely monitoring of temperature, light and humidity in datacentres, server rooms - or any space that relies upon a steady and predictable environment and has access to the internet. The Websensor series are sensors with built-in signal conditioning and a web address. Users are able to access the sensor directly via PC and remotely monitor the data which can be viewed at any time through a web-browser and receive alarms via text or email.
The Websensor EM01B connects directly to your Ethernet network via a 10/100 Mbps switch or hub port. It provides monitoring for temperature, illumination (light level) and relative humidity and is ideal for monitoring environmental conditions in server rooms and wiring closets. It is capable of measuring DC voltages, which allows you to check battery supply voltages of UPS units or renewable energy sources. The new thermistor interface allows you to interface external special use sensors, such as liquid temperature measurement and the new contact closure detection allows you to detect door open conditions (for security purposes) or configure equipment start-up and shut-down conditions.
The EM01B has an ESbus enabling other external sensors to connect to the web for remote monitoring. Each EM01B with its ESbus is capable of handling up to six additional ESbus enabled sensors. The EM01B is supplied complete with manuals, software for set up and cables. At time of ordering the customer must specify what additional function is required of those available: i.e. door contact, DC voltage, thermistor interface.
All alerts are operated by Nagios. The plugins are available within the downloads section of this page.
