Ajax LifeQuality Black Wireless CO2, Temperature & Humidity Monitor

Ajax LifeQuality Black Wireless Air Quality Monitor

The Ajax LifeQuality Jeweller is a wireless indoor air quality detector that tracks temperature, humidity, and CO2 concentration in real time. Designed to integrate seamlessly with an Ajax security and automation system, this compact black sensor helps homeowners, office managers, and facility operators maintain a healthier, more comfortable indoor environment while feeding data straight into the Ajax app.

Key Features

• Medical-grade CO2 sensing: Uses a non-dispersive infrared sensor to deliver accurate carbon dioxide readings that stay reliable even in the presence of aerosols or steam.
• Precision temperature and humidity tracking: An industrial-grade Sensirion SHT40 sensor measures conditions with tight accuracy, isolated on the board to avoid interference from other components.
• Once-a-minute measurements: Temperature, humidity, and CO2 levels are sampled every 60 seconds for near real-time monitoring.
• LED status indicator: A built-in touch-sensitive LED changes colour to show current air quality at a glance, from normal to critically polluted.
• Long-range wireless connection: Communicates with the Ajax hub over the Jeweller radio protocol, with a signal range of up to 1,700 metres in open space.
• Cloud history and trends: Readings are stored on the Ajax Cloud for up to two years, letting users review charts and trends by hour, day, week, month, or year.
• Automation-ready: Can trigger connected Ajax devices such as WallSwitch, Relay, or Socket to switch on ventilation, humidifiers, or heating automatically when thresholds are exceeded.
• Tamper and security protections: Includes an accelerometer for tamper detection, two-way communication, spoofing protection, and encrypted data transmission.
• Flexible mounting: Can be wall-mounted, ceiling-mounted, or simply placed on a flat surface using the included SmartBracket.

Where It's Used

LifeQuality Black suits homes, offices, schools, and commercial spaces where indoor climate directly affects comfort, health, or productivity. It's commonly installed in bedrooms, living areas, meeting rooms, and workspaces to catch CO2 build-up from poor ventilation, monitor humidity for mould prevention, and confirm comfortable temperatures - all while feeding into a broader Ajax intrusion, fire, or automation system.

Frequently Asked Questions

Does LifeQuality work on its own?
No, it requires a compatible Ajax hub (such as Hub 2, Hub 2 Plus, or ReX 2) to operate and communicate with the Ajax app.

Can LifeQuality control other devices automatically?
Yes, when paired with Ajax automation accessories, it can switch on ventilation, heating, or humidifiers when set thresholds for CO2, temperature, or humidity are exceeded.

How long is air quality history stored?
Readings are kept on the Ajax Cloud for up to two years, so you can review long-term trends directly in the app.
