CO2 Controller - With temperature and humidity sensor
Maintain the perfect indoor environment effortlessly with the InAir CO₂ Controller. Designed for precision and ease of use, this smart controller continuously monitors both CO₂ levels and temperature, automatically activating fans and alerts to keep your space safe, comfortable, and healthy.
Key Features:
Automatic Fan Control: Keeps CO₂ and temperature within optimal ranges by turning ventilation on or off as needed.
Smart Alerts: Audible buzzer notifies you instantly when CO₂ or temperature exceeds safe levels.
Customisable Settings: Adjust mid-values and ranges to suit your specific space requirements.
Dual-Parameter Monitoring: Works simultaneously for both CO₂ and temperature, ensuring a consistently safe environment.
With the InAir CO₂ Controller, you can relax knowing your indoor air quality and comfort are under intelligent control—reducing risks, enhancing wellbeing, and improving efficiency.
Functions:
1. Understanding the terms
CO₂ mid-value: This is the target or “ideal” CO₂ level you want to maintain.
CO₂ range value: This is how much variation around the mid-value is acceptable.
The formula CO₂ mid-value + CO₂ range value / 2 essentially sets an upper threshold for CO₂.
Temperature mid-value: The target temperature you want.
Temperature range value: The acceptable variation around the temperature target.
The formula temperature mid-value + temperature range value / 2 sets an upper temperature threshold.
2. CO₂-based operation
Fan and buzzer ON: When CO₂ > (mid-value + range/2).
This means CO₂ has risen above the upper acceptable limit. The system responds by turning on the fan to lower CO₂ and activating the buzzer as an alert.
Fan and buzzer OFF: When CO₂ < (mid-value + range/2).
This means CO₂ is back below the threshold, so the fan stops, and the buzzer turns off.
3. Temperature-based operation
Fan and buzzer ON: When temperature > (mid-value + range/2).
This triggers the fan to cool things down and the buzzer as an alert.
Fan and buzzer OFF: When temperature < (mid-value + range/2).
Temperature is back under control; the fan and buzzer stop.
4. Combined operation
If either CO₂ OR temperature is above their respective upper threshold:
Fan turns ON, and buzzer activates.
Only when both CO₂ and temperature are below their thresholds:
Fan turns OFF, and buzzer deactivates.
5. Simplified logic in words
Check CO₂ and temperature against their thresholds.
If any threshold is exceeded → Fan ON, Buzzer ON.
If both are under threshold → Fan OFF, Buzzer OFF.
