Cooala

The Cooala is an electronic CO₂-Alarm - hence the name: COO-Ala-rm. Scientific studies suggest that the concentration of the dreaded corona aerosols in closed rooms increases very quickly to a worrying level - whether with or without a mask - and unfortunately vaccination does not offer perfect protection either.

At the same time, however, it was found out that the aerosol concentration is similar to the CO₂-Concentration increase. Even if it is unfortunately not possible to “measure” Covid virus concentration directly and quickly today, the CO₂-concentration may be determined easily and inexpensively.

This is where the idea for Cooalastems from: A simple, inexpensive and yet effective solution to reduce CO₂ in classrooms, offices, buses or even in your own living room₂-Concentration visible and pragmatic to remind you of the easiest way to reduce the virus and bacteria concentrations that may be too high: Burst ventilation!

Scientists specifically point out that only the so-called Cross ventilation effectively ensures that the accumulated pathogens are removed from the room as quickly as possible. Long “tilt” ventilation is by far not as effective. But what to do when it gets colder outside? Or loud? Or if the ventilation is simply forgotten?

The Cooala provides a powerful yet simple countermeasure: A display reminiscent of a thermometer permanently provides an intuitive indication of the current air quality: the “higher” the CO₂Concentration, the higher the display bar rises - and even turns yellow and red when specific thresholds are reached - in fine gradations and therefore more informative than a CO₂-Traffic light. Human intervention is required now: Open the windows and doors immediately!

Standard measuring devices offer - at a sometimes very high price! - only display unintuitive representations and are not suitable for everyday school or office life. We have set ourselves the goal of offering a simple and inexpensive solution that makes it easy for teachers, parents, bosses and employees to permanently remind them of appropriate air hygiene. This does not guarantee against infection with Corona - but it can help to greatly reduce the risk of infection.

The Cooala is available in different versions:

The Design Edition the sensor is in a small box in the power cable. Only the approx. 25cm long aluminum display unit is visible. This can be integrated homogeneously in any school, office or private environment and still gives you the certainty that you are reminded of timely ventilation

to become.

The Kids Edition was specially developed for the elementary school sector, since the emotional aspect is also highly relevant here: The Cooala can be integrated directly into the day-to-day routine - the new mascot in difficult times!

In addition, the Retro Edition available: Here the Cooala is based on an analogue thermometer. The sensor unit is directly connected to the display unit. A simple wall mounting is immediately possible here.

All editions have in common: Immediately after connecting to a USB power supply unit or a power bank, the Cooala starts working:

• Display of the CO2 concentration on a 14-element segment display.
• Configurable warning values: As standard, the display turns yellow from 700ppm, red from 1200ppm - and, as a non-ignorable warning, flashes red from 1600ppm. These values are based on the recommendations from researchers.
• Automatically coupled with the optional Cooala control center: This can be connected directly to an HDMI television or monitor and prominently displays the air quality of the individual measuring stations. In addition, the CO2 development over time can also be monitored from here in the form of a diagram - or, if required, the alarm values of all stations can even be adjusted.
• About the Cooala Hub the measured values can be displayed retrospectively. This means that it can be made credible at any time that the ventilation recommendations have been complied with. This creates trust with parents, customers and the general public.

The main properties are summarized on the One-pager compiled, which can also be downloaded and printed out as a PDF.

Using the Cooala is very simple: The display unit can be attached directly to a smooth wall using pre-assembled acrylic adhesive dots. The power cable is connected to a USB power supply unit or power bank - done! See also the further technical information.
