PPM Technology’s latest indoor air quality (IAQ) monitoring system, the Wireless IAQ Profile PPMonitor, is claimed to enable simple, effective and flexible management of the indoor air environment.

The PPMonitor can continuously detect, measure and record a number of parameters, including temperature, humidity, formaldehyde, nitrogen dioxide, carbon monoxide, carbon dioxide, sulphur dioxide, ozone, ammonia and TVOCs.

Real-time functions enable immediate warnings of the presence of harmful gases in the air, thus protecting employees and the public; buildings can be immediately evacuated, providing minimal exposure to the building occupants.

The PPMonitor system has been designed to be easy to set up and operate.

A manager PC simply connects to the wireless network using a Telegesis Zigbee USB module, allowing transmission and receiving of information to and from a particular wireless unit.

The wireless units communicate via the Zigbee wireless mesh network.

The network can be extended by adding repeater nodes or additional PPMonitor or Mini PPMonitor units; each unit can be configured with unique sensor specifications if required.

This allows complete monitoring of the indoor air environment in any building layout.

One unit is connected to the building management system (BMS).

BMS software allows the entire wireless system to be managed from a single PC, which can preset a number of different exposure levels to trigger when limits are exceeded; these could be visible or audible alarms or to control third-party systems such as ventilation.

The PPMonitor software enables the data to be viewed graphically and can be used to produce reports and statistical data.

Analysis of the recorded data over time allows for more efficient management of resources and energy.
