AIR-1 Air Quality For Home Assistant - with CO2 and Gas sensor

The Apollo AIR-1 with CO₂ and gas sensor is a compact Wi-Fi air quality monitor that delivers detailed insight into your indoor environment. At just 61 x 61 x 30 mm, it combines a discreet design with powerful sensing technology. The pre-calibrated SCD40 CO₂ sensor ensures accurate tracking of carbon dioxide levels, while the MiCS-4514 gas sensor expands detection to carbon monoxide, methane, ammonia, nitrogen dioxide, ethanol, and hydrogen.

Together, these sensors allow you to spot changes in air quality quickly, from elevated CO₂ to traces of household gases or fumes. Perfect for triggering automations in Home Assistant and other platforms, you can set your system to ventilate, run an air purifier, or send you alerts when conditions shift. Alongside gas and CO₂ data, the AIR-1 also measures temperature, humidity, and barometric pressure, giving you a complete picture of your indoor air.

Powered via USB-C, the AIR-1 connects directly over Wi-Fi with no need for cloud services or subscriptions. With open-source firmware and shared CAD files, it invites tinkering and customization, making it as flexible as it is precise. For anyone who wants reliable monitoring and advanced smart home integration, the AIR-1 with CO₂ and gas sensor is a standout choice.
