Wellbeing at work with connected objects

Humidity, temperature, but also carbon dioxide can be responsible for certain inconveniences and are not always synonymous with well-being at work. Carbon dioxide is an odourless gas with a neutral taste that is only perceptible to humans through its harmful properties: malaise, lack of concentration and reduced performance. The inhaled air contains 21% oxygen and 0.03% carbon dioxide. On the other hand, exhaled air contains only 17% oxygen and 4% carbon dioxide.

Indeed, if carbon dioxide becomes toxic to humans from a concentration of 2.5%, there is already a reduction in performance, concentration and well-being from a concentration of 0.08% (800 ppm) carbon dioxide.

In enclosed spaces, such as classrooms, offices or meeting rooms, or in areas where there is no ventilation system, it can be difficult to know when to ventilate. But when several people congregate, it only takes a few minutes to reach values in the range of 5,000 to 6,000 ppm of carbon dioxide.

Above 1000ppm, we already note a decrease in psychomotor capacities with premature fatigue and a declining ability to concentrate. Hypercapnia occurs when the blood vessels are overloaded with CO2, which causes several undesirable effects such as sweating, high blood pressure, consciousness disorders, attention deficit and drowsiness.

Finally, when we reach very dangerous CO2 risk levels at work (or elsewhere) such as 10000ppm for example, human beings are in real danger.

Thanks to the internet of things, with the Ewattch Ambiance sensor you can have optimal working conditions and know in real time when this threshold is exceeded with its LED indicator which is activated from a configurable threshold. Other means of signalling can be applied with the sending of mail or SMS for example.

In France, “Title III of the Departmental Health Regulations (RSD) sets, for non-residential buildings, a CO2 threshold of 1,000 ppm under normal occupancy conditions, with a tolerance of 1,300 ppm in premises where smoking is prohibited and in the workplace, without an explicit health basis for these two values”.

In addition, although there is no specific regulation, today, at the level of the labor code on the maximum value of CO2 (ppm) in France in the premises, you can see below, however, that there are standards of the European Union that have been established in terms of CO2 concentration in the premises for the well-being:

The CO2 absorbs part of the infrared radiation emitted towards the sensor. The sensor uses the refraction of light to detect the gas and measure the CO2 concentration. This measurement technique is more commonly known as non-dispersive infrared (NDIR)

Installed by wall mounting and with an autonomy up to 10 years, our Ambiance connected sensor, is a real concentrate of technologies and allows to measure :

– Indoor temperature from 5 to 60° C

– The humidity level inside your building from 0 to 100%.

– CO2 in offices or any other room (from 0 to 5000 ppm)

– Brightness from 0 to 65535 Lux

– The attendance rate of your buildings with the presence detection function

– Communicate wirelessly via LoRa or LoRaWAN network

– Participate in the well-being at work

With Ewattch, the IoT is at the service of mankind!
