A contaminant in the indoor air? The Renson Sense will tell you!

Do you know how healthy the indoor air is in your home, office or children's classrooms? Hard to say, isn't it? The CO₂-content in the air teaches you a lot about that, but the problem is that you have CO₂ cannot smell if you stay in the same room for a long time and certainly cannot see it. That's why Renson is launching the Sense, a smart CO₂-meter that lets you know when indoor air quality is deteriorating and thus it is time to ventilate.

Exhaled air, moisture and pollutants

CO₂ is in the air we breathe out. And although moisture and pollutants also help determine indoor air quality, CO₂ - especially with many people in the same room - a good indicator of indoor air quality. If that CO₂-level rises alarmingly high, this is because it means that the exhaled air of those present is not being adequately refreshed. Especially in airtight, well-insulated and unventilated spaces, that CO₂-content quickly rises above 1,200 ppm (parts per million). And then you can no longer speak of healthy indoor air. By comparison, outdoor air typically contains 400 ppm of CO₂. Indoors, a maximum of 800 ppm is ideal, 1000 ppm is acceptable and 1200 ppm is an upper limit to speak of healthy indoor air.

Measuring is knowing: the Sense does it for you

But then, how do you know when it's high time to open a window and change the indoor air if a ventilation system doesn't do it automatically in your place? Because by yourself, for CO₂ unfortunately no "sixth sense. Fortunately, Renson's new Sense does. This clever sensor keeps track of CO₂-level in the indoor air constantly in the (digital) eye and indicates when it rises too much. If the air is healthy, the sensor lights up blue. In the case of a CO₂-level between 800 and 1200 ppm you get an orange color as a warning that air quality is getting worse. And red means the amount of CO₂ in the air has exceeded the 1,200 ppm limit for healthy indoor air. In that case, you should ventilate the room intensively as soon as possible by opening windows and doors. Or you need to look for a suitable, energy-efficient ventilation system so that you can always breathe healthy indoor air even in winter without driving up your heating costs.

More than a CO₂-meter

But the Sense is more than a visual CO₂ meter. The device also charts other parameters that contribute to a healthy and comfortable indoor climate, such as the amount of pollutants, temperature, humidity and light levels. Also convenient: you can monitor all parameters in real time via the corresponding app on your smartphone and call up the history. In this way, you can find out whether your home is also suffering from other structural problems that need to be addressed urgently.
