Air monitoring with LifeQuality

Issue 1 2023 Perimeter Security, Alarms & Intruder Detection, Products

Ajax Systems has launched LifeQuality, a smart air quality monitor that combines medical-grade measurement accuracy and professional security technologies. The device provides users with data on carbon dioxide pollution, temperature and humidity levels, and helps automate appliances according to these indicators.

“Many studies prove that carbon dioxide levels strongly affect the brain’s functioning. In particular, productivity. For example, a high concentration of CO2 can reduce the speed of mental activity by 60% and the ability to make complex decisions by 50%. The problem is clear: bad air kills productivity. It has been tested in schools, offices and even on the space station,” said Max Melnyk, Device Department R&D; Director, Ajax Systems.

LifeQuality is explicitly designed for building an extensive air quality monitoring system. The monitor is equipped with an accelerometer, notifying users if it moves to another location. Moreover, the SmartBracket helps to easily mount it on the wall in every room or office. LifeQuality works on a battery for up to three years, so there is no need for a power outlet in the place of installation.

Medical-grade measurement accuracy

LifeQuality is packed with sensors that are used in professional medical equipment. Sunrise from Senseair is a non-dispersive infrared sensor that directly measures carbon dioxide concentration. Unlike VOC sensors, this type of sensor indicates actual and precise CO2 data regardless of pollutants in the air, like aerosols and steam.

SHT40 from Sensirion is an industrial-grade digital sensor platform for measuring relative humidity and temperature. An integrated heater allows for advanced on-board diagnostics, and the sensor element is designed for harsh conditions such as condensing environments. SHT40 ensures up to ±0.2°C accuracy.

The air quality indicators are displayed in the Ajax app alongside information on security and automation devices. Thanks to the Ajax Cloud server, security system users can access data from anywhere. The indicators are accompanied by charts containing the history for several days, a week, a month or even a year, helping to understand air quality dynamics. Push notifications give users instant awareness of environmental changes according to set thresholds.

Due to the in-built memory, LifeQuality can be used to measure the air quality in other locations, for instance, a garage, kindergarten, and relatives’ houses. Even without communication with an Ajax hub, the monitor stores data for three days. When the connection is restored, all data is uploaded to the hub, and users can view it in the app.

Aside from the app, the device LED indicator instantly reports carbon dioxide levels. A user just has to tap the Ajax logo. It glows yellow, red or purple if the concentration of CO2 exceeds the set norm.
