CO2 Indicator - SCHOOL

CO₂ Traffic Light SCHOOL – The Green Ventilation Indicator for Fresh Air and Alert Minds in the Classroom

Children should learn, not yawn – the CO₂ Traffic Light SCHOOL from Elektrotechnik Schabus makes exactly that possible. 

From 1,000 ppm it lights up yellow = “Ventilate now!”, from 2,000 ppm red + warning tone = “Ventilate immediately!”. High-precision NDIR infrared sensor, automatic night dimming, extremely low power consumption. Mount on the wall at a height of 1.8–2 m, away from doors and windows, plug in the power supply – ready after 3 minutes. 

Durable green housing, with optional anti-theft protection and ball-proof guard available as accessories. 

Important: keep it permanently powered on – the traffic light automatically calibrates itself at night based on the lowest CO₂ concentration measured over the last 7 days. 

The technology is as simple as it is smart: yellow from 1,000 ppm – exactly the level where children start losing concentration. Red + tone from 2,000 ppm – well before any health limit (MAK 5,000 ppm). This ensures ventilation happens neither too late nor too often, saving heating energy that would otherwise go out the window. The light sensor dims the LEDs automatically at night, and the auto-calibration makes use of quiet periods. 

Complies with EU standard EN 13779 for schools and public buildings. Once installed, it operates maintenance-free for years – teachers only need to look, not guess.

The CO₂ Traffic Light SCHOOL is more than a lamp – it’s the silent break monitor. Thirty children can make a classroom stuffy within 20–30 minutes. Without the indicator, lessons continue even though everyone is tired. With it, the window opens just at the right time – and closes again when the light turns green. 

Teachers appreciate the clear feedback, janitors enjoy lower heating costs, parents love the alert children. And the students? They just notice: “Today I can focus again!” 

The CO₂ Traffic Light SCHOOL at a Glance:

• Yellow from 1,000 ppm: Early and clear reminder to ventilate.
• Red + tone from 2,000 ppm: Immediate action required (sound can be muted).
• NDIR infrared sensor: High precision, long-lasting, maintenance-free.
• Auto-calibration: Uses night-time data – always accurate (never unplug!).
• Night dimming: LEDs switch off automatically in darkness – extremely energy-efficient.
• Durable green housing: Standard green, optional RAL colors available.
• Accessories: Ball guard, anti-theft device, and stand available.
• Made in Germany: Highest quality and reliability from Schabus.

Applications: Where the CO₂ Traffic Light SCHOOL Ensures Fresh Air

• Classrooms of all types: From primary schools to high schools – alert children guaranteed.
• Assembly halls & common areas: Large spaces, many people – one indicator often suffices.
• Gyms & sports halls: High activity levels – quick ventilation required.
• Staff rooms & administration offices: Adults benefit too.
• After-school & day-care rooms: Long stays – consistently good air.
• Music & art rooms: Many occupants, few windows – perfect air tracking.
• Public buildings with visitors: Offices, libraries, youth centers.

With the CO₂ Traffic Light SCHOOL, proper ventilation in the classroom becomes child’s play – and heating costs stay where they belong: inside the room. Yellow = open window, green = continue learning. Staying focused has never been this easy.
