Wireless IAQ Profile Monitor

The Wireless IAQ (Indoor Air Quality) Profile Monitor is the latest monitoring unit to be launched by PPM Technology Ltd to assist with all your IAQ monitoring applications and requirements.

The IAQ Profile system has been designed to give a visual representation of indoor air quality in buildings, as part of the buildings management standards in relation to conditions such as Sick Building Syndrome. Since a great number of units can be networked, the system can show prescise changes in concentration of selected IAQ parameters in various locations over time. The IAQ Profile Monitor system enables the user to control and run several wireless IAQ sampling units — all communicating together via the sophisticated and reliable ZigBee wireless mesh system. The mesh network system is costeffective, easy to install and simple to use: the nodes which make up the mesh automatically configure the optimal signal route. Other advantages of a wireless mesh system is that it is self healing meaning that the network can still operate even when a node breaks down or a connection goes bad. As a results, a very reliable network is formed. The size of the wireless mesh can be easily extended by simply adding new IAQ Profile Monitor units as each one is also a router for it's neighbours. In areas where no IAQ monitoring is required then dedicated "Repeater" nodes can be used for the same purpose. Power Amplified Wireless Modules are also available, these have more powerful antennae to considerably increase the transmission distance and consequently reducing the need for repeaters and simplifying the network.

Each IAQ Profile Unit can monitor 3 to 8 different IAQ parameters. The Manager PC connects to the mesh network via a special node which is capable of recieving and transmitting information to the IAQ Profile Monitor. The Manager PC can view, run and control the realtime monitoring and data logging of air quality in a bulilding at the click of a button. The PPMonitor software enables the data to be viewed graphically, produce reports and statistical data, run schedules as well as alarm functions and notifications for more effective and economical building management. It is possible to set up an Ethernet Access Point (EAP) to the wireless network which allows the wireless modules to be accessed from any location world-wide via the Internet provided the necessary internet address, firewalls and gateways are enabled on the local network. Sensor Configuration:

  • Formaldehyde
  • Temperature
  • Humidity
  • Nitrogen Dioxide (NO2)
  • Carbon Monoxide (CO)
  • Carbon Dioxide (CO2)
  • Sulphur Dioxide (SO2)
  • Total Volatile Organic Compounds (TVOC's)
  • Ozone (O3)
* Other sensor options available

The IAQ Profile Monitor incorporates a variety of advanced gas sensor technologies to monitor the target gases including NDIR, PID and Electrochemical.
