Arley
A clever air sensor that ‘sees’ what we cannot. He translates the science of air into colors: green means clean air, yellow means caution, red means time to clean the air!
Want to talk to me about the air we breathe?
Arley is a smart and very clever air sensor with the superpower of ‘seeing’ what our eyes cannot. With his compact body and his magic lights, he is always on watch to make sure the space is safe for playing and learning.
Arley’s mission is to translate the science of air into colors that everyone understands:
- 🟢 Green Light: The sign of victory! The air is nice and clean and the villains are gone.
- 🟡 Yellow Light: Full attention! Arley is warning us that the air is starting to feel heavy and we need to stay alert.
- 🔴 Red Light: Time to clean the air! The air outside may be polluted, or opening the windows may not be an option.
