Web Graph Air Quality - temperature, humidity and air quality (VOC) online
Web Graph Air Quality is an IP device for measuring temperature, humidity and air quality (VOC).
 
Alarms and measured values via e-mail, SNMP traps, FTP, ...
 
Most is measured in office buildings, schools and similar décor CO2 for ventilation control - but the CO2 measurement does not consider the actual air quality (odor). The VOC sensor, indoor air quality can, however considering the human perception determine.
 
VOC (Volatile Organic Compounds): volatile organic compounds voliegen at room temperature in gas or vapor form in the air.
Many solvents and materials synthesis can occur as VOC, as well as numerous organic compounds that are formed in biological processes. Humans and animals enter the latter from about breathing or directly through the skin.
 
 
Features
  • Configurable LED light at the sensor for optical signaling of limits
  • Alarms and reports via e-mail, SSL / TLS Encryption
  • Device language selectable German / English
  • Temperature monitor via a web browser (design of HTML pages can be customized)
  • time synchronization
  • 10/100 MBit
  • SNMP polling / Alarm traps for temperature, humidity and air quality standards for incorporating into your existing SNMP management system
  • AJAX, JavaScript
  • TCP and UDP sockets, client and server
  • OPC server
  • SYSLOG
  • FTP (data logging)
  • can tweet the metrics in your Twitter account
  • Measurement data online in the free anger-cloud

 

Easy installation

 

Connect the sensor and the network cable, assign the device an IP address to or refer them via DHCP from your network, and the device is ready for use!
