Ajax LifeQuality monitors the air quality in the room
Ajax LifeQuality measures temperature, humidity and CO₂ levels in real time. Poor air quality can affect your health and concentration. High CO₂ levels can lead to fatigue, headaches and reduced decision-making ability.
What does LifeQuality measure?
CO₂ concentration: The sensor measures carbon dioxide levels from 400 to 10,000 ppm (parts per million). This gives a very accurate picture of the room's air quality.
Temperature: The built-in temperature sensor measures from 0 °C to +50 °C with an accuracy of ±0.2 °C. You can set thresholds in the app so you get a notification if the temperature falls outside the set limits.
Humidity: It detects humidity from 0% to 100% with an accuracy of ±1.8%. Monitoring humidity can help prevent mold, discomfort and dry air. You can create scenarios where a dehumidifier or humidifier is automatically activated if the humidity reaches a critical level.
All measurements are logged in the app, where you can later view a detailed graph of the readings.
Automatic activation of ventilation and humidifier
By combining LifeQuality with other Ajax devices such as WallSwitch or Socket, climate control can be activated completely automatically. In the app you can create scenarios that trigger when the CO₂ level, humidity or temperature reaches a certain threshold. That means the sensor can detect changes in the indoor climate and activate connected devices.
Examples of automation scenarios
Ventilation activates when indoor air quality is poor: If the CO₂ level exceeds 1,200 ppm (parts per million), a fan or a mechanical ventilation system can be turned on via WallSwitch.
Dehumidifier or humidifier starts automatically: If humidity falls below 30% or rises above 60%, a humidifier or dehumidifier can be activated via Socket.
Adjust temperature automatically: If the room temperature falls below 18 °C, a heat source such as an electric radiator or underfloor heating can be turned on. Conversely, a fan or air conditioner can be started if the temperature exceeds a set limit.
The importance of air quality
| CO₂ level | Effect |
|---|---|
| 400-1000 ppm | Normal air quality |
| 1001-1400 ppm | Tiredness and difficulty concentrating |
| 1401-1999 ppm | Headache, dizziness |
| 2000+ ppm | Decision-making ability significantly reduced |
Easy installation
LifeQuality can be placed on the wall, in the ceiling or on a table. It works wirelessly and is simple to install. The sensor is also portable and can be used temporarily in other places – for example in the car, summer house or basement.
Range
LifeQuality communicates wirelessly with the hub via Jeweller and Wings technology and has a range of up to 1,700 meters in open terrain. If the sensor loses connection to the hub, it can store all measurements for up to 3 days. This ensures that no data is lost, even during a temporary connection interruption.
Battery life
The sensor is delivered with a CR123A battery with a life of up to 2.5 years. The lifetime depends on several factors:
- How much it's used – More frequent measurements and scenarios can shorten battery life
- Temperature – Very cold conditions can reduce the battery's performance
- Battery quality – High-quality batteries typically last longer than standard batteries
Tamper protection
If someone tries to move the sensor, it will immediately send a tamper alarm to the hub.
