Why Airis stands above the rest: multi-wavelength temperature analysis

Airis technology is a decade in the making—tried, tested, and trusted. But what really sets it apart from other stove guards? The answer lies in its cutting-edge sensors, which tackle a fundamental issue that most other devices overlook. If you’ve ever wondered about the technology that puts Airis in a league of its own, you’re in the right place.

The problem with traditional stove guards

Most stove guards measure temperature, but they do so in a way that leads to inaccurate readings. The result? Devices that either fail to detect overheating pans in time or interrupt cooking unnecessarily.

The issue is simple: not all cookware radiates heat the same way. A stainless-steel pan and a cast-iron skillet at the same temperature will emit vastly different infrared signals. Basic sensors, which rely on single-wavelength temperature measurements, struggle to distinguish between these variations. This can lead to dangerous situations where a real fire hazard goes undetected or, conversely, where the stove guard triggers false alarms, frustrating users.

The most important consideration for hob safety is to ensure that the temperature of cookware does not rise so high that an oil fire ignites. You would have seen from our blog that different oils ignite at vastly different temperatures, but the real challenge is to ensure that safe, normal high-temperature frying with the right oil can continue if there’s no danger to the user, allowing them to continue without annoying interruptions from inferior safety devices.

Recognising these shortcomings, Safera—the brains behind Airis—developed an innovative, patented solution that ensures accurate and reliable stove safety.

Why pan temperature matters

Cooking safety isn’t just about monitoring surface heat; it’s about preventing temperatures from reaching ignition points. Different oils ignite at different temperatures, and safe frying should not be disrupted unnecessarily. A reliable stove guard must identify overheating risks without interfering with normal cooking, but that’s easier said than done.

Different materials radiate heat in different ways. Black cookware, like cast iron or Teflon-coated pans, emits heat strongly, while shiny stainless-steel pans reflect much of it. Standard infrared sensors struggle to account for this variation, making accurate temperature readings across multiple pans nearly impossible. This is where Airis excels.

How Airis solves the problem

Unlike conventional stove guards that rely on single-wavelength infrared sensors—or even multi-pixel sensors that only map temperature differences—Airis uses a completely different approach:

1. Multi-wavelength analysis

Airis measures multiple wavelengths of infrared radiation simultaneously. By applying Planck’s Law, which describes the way in which objects radiate heat based on their temperature, Airis accurately detects the real temperature of any cookware, regardless of material.

2. Dynamic temperature tracking

Instead of relying on static readings, Airis tracks temperature changes over time, identifying dangerous heat trends in real time. This means it can instantly detect when a pan is overheating—even among multiple pans in use.

3. Smart response system

By accurately assessing risk levels, Airis only intervenes when necessary, ensuring seamless, uninterrupted cooking for users. Whether you’re using a Teflon-coated frying pan, a steel kettle, or a cast-iron pot, Airis makes sure you cook safely without nuisance alarms.

Airis in real-world cooking

Airis is not just a theoretical breakthrough—it’s making a real impact:

• Elderly and vulnerable users – Many people with cognitive or physical impairments rely on Airis to maintain their independence while staying safe from cooking-related fire hazards.
• Student accommodation – University halls across the UK have installed Airis, ensuring thousands of students can cook safely without unnecessary fire alarms or risks.

The most advanced stove guard on the market

By now, you’ve seen why traditional stove guards fall short and why measuring cookware temperature accurately is no simple task. Airis solves this problem with multi-wavelength infrared sensing, real-time tracking, and a smart intervention system. It’s not just the most advanced stove guard available—it’s also the least disruptive, making cooking safer without interfering with the process.
