Your Personal
Air Guardian
BioSense™ Watch is the world’s first smartwatch capable of reporting an
, giving you unparalleled awareness of your surrounding environment!
Whether you’re navigating a polluted city or ensuring your home remains a safe sanctuary, BioSense Watch gives you the power to know like never before.
Unlike AQI measurements you might see on the local news or on your phone, the AQI reported by your BioSense Watch is personalized to you!
This device is uniquely able to provide real time AQI for the air you are breathing everywhere you go because the sensors are on your wrist!

It’s all possible thanks to three advanced, German-made sensors inside the Red Dot Award-winning design of BioSense Watch. These microsensors continuously scan for harmful substances, including:

- An Indoor measurement with BioSense Watch reports an overall score, TVOC, EtOH, and perceived temperature and humidity.
- TVOCs are responsible for the odor of scents and perfumes as well as , and are found in common household sources, including tobacco smoke, paint, nail polish, adhesives, and household cleaners.
- If EtOH vapors accumulate in enclosed spaces or are released in high concentrations, they can contribute to indoor . This is especially true in poorly ventilated areas or when using products containing high levels of ethanol, such as certain cleaners or solvents.
- CO₂ concentration cannot be directly measured by the MEMS MOX sensor. However, there is a strong correlation between and TVOC levels caused by indoor human occupancy. Therefore, we calculate estimated CO₂ (eCO₂) using our robust, patent-pending algorithm using this correlation.
is captured manually, either initiated on BioSense Watch or through the Vyvo Smart App.

- An Air Quality measurement with BioSense Watch reports an overall score, ozone, EPA AQI, and perceived temperature and humidity.
- Ozone is not emitted directly into the air but is formed by chemical reactions between oxides of nitrogen and VOCs in the presence of sunlight.
- O3 can have significant effects, particularly on the respiratory system.
- The EPA's Air Quality Index (AQI) provides an overall assessment of outdoor based on the concentrations of several pollutants, including ground-level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide.
- To adapt BioSense Watch to a possibly fast-changing and fluctuating circumstance, the EPA measurement used level 1 and 2 of the original EPA measurement.
is captured manually, either initiated on BioSense Watch or through the Vyvo Smart App.

- Because BioSense Watch acts as a wearable air quality monitor, it is mostly used in fast-changing, fluctuating, and complicated circumstances. The wearer is likely to frequently move between indoor and outdoor environments, and the defining line between and is hard to distinguish. For example, if someone is sitting inside next to a widely opened window. For this reason, we also employ a , which reports the air quality based on all the results from the sensors, considering all measured gasses, IAQ, OAQ, temperature, humidity, etc.
- The is the best possible representation of the air quality immediately around the device user at any given moment, reported every 10 minutes. Equipped with this information, the device user can make informed decisions about whether to exercise, and which is the best location, indoors or out. reports an overall measurement and data for ozone; EPA, TVOC, eCO2, and EtOH, plus perceived temperature and humidity.
