Usage:
The sensor and air quality control system is ideal for residential, commercial, and industrial spaces where constant air quality must be maintained. The sensor measures CO2, temperature, and humidity to automatically regulate fans or valves according to set parameters. The system is used to improve air quality, reduce energy costs, and create a healthier working and living environment.

Pros:

Precise air quality control: Adjusts the ventilation system based on CO2, temperature, and humidity levels.
Remote control: RS485 module allows remote control of the system, integrating it with smart home and building management systems.
Energy-saving: Requires minimal energy due to its low-power control system.
Automatic and manual control: Flexible management with automatic, manual, or timer modes.
Protection and durability: The device is fire-resistant (V0) and reliable in challenging conditions.
Easy installation: Compact dimensions and simple installation.
Cons:

Only RS485 communication: Supports only the RS485 communication standard, which may limit integration with some older or different systems.
Need for additional accessories: Full functionality may require additional devices or integration services.
Not recommended for very large spaces: While suitable for most medium-sized rooms, larger spaces may require additional devices.
