High quality sensor

We purchased three more of these after acquiring the first one last month. We compared its CO2 readings to a more expensive device we purchased as our office suffers from high levels of CO2. Very reliable device with a refreshingly simple design.

Super petit produit !

Un produit bien pensé et élégant. Le câble est long, ce qui m'arrange, même si j'aurais préféré encore plus long. La batterie semble durer plusieurs jours, mais je préfère laisser brancher pour ne pas avoir à y penser. Sonnerie à 1500 ppm pour m'alerter trsè pratique

FAQs

Please read our FAQs page to find out more.

What is a CO2 sensor and what is it used for?

A CO2 sensor is a device designed to measure the concentration of carbon dioxide (CO2) in the air. It is used to monitor indoor air quality and to ensure that CO2 levels remain within acceptable ranges for both health and comfort.

If CO2 levels are too high, it means that the oxygen levels are insufficient for your comfort and health.

Why is it important to monitor CO2 levels in the air?

High levels of CO2 in the air can indicate a lack of ventilation and a build-up of pollutants. This can lead to decreased concentration and productivity, headaches, increased fatigue, and other health problems. Elevated CO2 levels are also associated with an increased risk of airborne germs contamination. Monitoring CO2 levels allows you to take action to improve air quality and occupant comfort, as well as protect their health.

How do I use a CO2 sensor?

A CO2 sensor is usually placed in a central location in the room at a height of approximately 0.8 to 1.8 metres (2.5 to 6 feet) from the floor. You can install the Eoleaf Smart CO2 sensor on a desk or mount it on a wall. Once installed, the sensor automatically monitors CO2 levels and provides alerts if predefined thresholds are exceeded (1500 ppm in our case).

Can I use the Smart CO2 sensor with my Eoleaf air purifier?

Of course! These two devices can be used simultaneously. In fact, it is recommended to use both devices together in order to achieve optimal indoor air quality.

Can I change the PPM level at which the alarm turns ON?

No, you cannot change the alarm. It will ring when you reach or exceed 1500 ppm, in line with World Health Organization (WHO) guidelines.

What do the different colour levels mean?

The Eoleaf Smart CO2 Sensor has a measuring range from 0 to 10,000 ppm.

  • Green: < 699 ppm (healthy)
  • Blue: 700-999 ppm (acceptable)
  • Orange: 1000-1499 ppm (poor)
  • Red: > 1500 ppm (dangerous)
