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 enclosed spaces rises very quickly to a worrying level – regardless of whether a mask is worn or not – and unfortunately, even vaccination does not offer perfect protection.

At the same time, however, it was found that the aerosol concentration was similar to that of CO₂.₂The CO₂ concentration increases. Even though it's unfortunately not possible to directly and quickly "measure" coronaviruses in the air these days, the CO₂ concentration can be measured.₂-Determine concentration easily and cost-effectively.

This is where the idea for Cooala. A simple, cost-effective, yet effective solution for reducing CO₂ in classrooms, offices, buses, or even your own living room.₂-To make the concentration visible and to pragmatically remind you of the simplest way to reduce potentially excessively high virus and bacteria concentrations: Shock ventilation!

Scientists specifically point out that only the so-called Cross ventilation This effectively ensures that accumulated pathogens are removed from the room as quickly as possible. Leaving windows slightly ajar for extended periods is far less effective. But what should you do when it gets colder outside? Or noisy? Or when you simply forget to ventilate?

The Cooala A simple countermeasure is offered: A display reminiscent of a simple thermometer provides a constant, intuitive indication of the current air quality: The "higher" the CO₂₂The higher the concentration, the higher the indicator bar rises – and when specific thresholds are reached, it even turns yellow and red – in fine gradations and therefore more informative than a CO₂ reading.₂-Traffic light. Human intervention is required now: Open the windows and doors immediately!

Conventional measuring devices – often quite expensive! – offer only unintuitive displays and are unsuitable for everyday use in schools or offices. Our goal here is to offer a simple and affordable solution that makes it easy for teachers, parents, managers, and employees to constantly remind everyone about proper air hygiene. This doesn't guarantee protection against COVID-19, but it can significantly reduce the risk of infection.

The Cooala is available in various versions:

The Design Edition The sensor is housed in a small box inside the power cable. Only the approximately 25cm long aluminum display unit is visible. This allows it to be seamlessly integrated into any school, office, or home environment, while still providing the reassurance of timely ventilation.

to become.

The Kids Edition It was specifically developed for primary schools, as the emotional aspect is also highly relevant here: The Cooala can therefore be directly integrated into the teaching process – the new mascot in difficult times!

Additionally, there is also the Retro Edition Available: The Cooala is modeled after an analog thermometer. The sensor unit is directly connected to the display unit. Easy wall mounting is possible immediately.

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

• Display of CO2 concentration via 14-element segment display.
• Configurable warning levels: By default, the indicator turns yellow at 700 ppm, red at 1200 ppm – and, as a non-ignorable warning, flashes red at 1600 ppm. These values are based on research recommendations.
• Automatically paired with the optional Cooala control unit: This can be connected directly to an HDMI television or monitor and prominently displays the air quality of each measuring station. Additionally, the CO2 development over time can be observed from here in graph form – or, if desired, the alarm values of all stations can even be adjusted.
• About the Cooala Hub The measured values can be displayed retrospectively. This makes it possible to credibly demonstrate at any time that the ventilation recommendations were followed. This fosters trust among parents, customers, and the 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 It's very simple: The display unit can be attached directly to a smooth wall using pre-mounted acrylic adhesive dots. The power cable is connected to a USB power adapter or power bank – that's it! See also the further technical information.
