Integrated Multi-Parameter Sensor (CO₂ / PM2.5 / TVOC / Temperature & Humidity Monitoring Module)

Real-time monitoring of CO₂, PM2.5, TVOC, temperature, and humidity for intelligent sensing, automatic adjustment, and refined control of indoor air quality and thermal comfort.

The integrated multi-parameter sensor combines CO₂, PM2.5, TVOC, temperature, and humidity sensing capabilities for continuous and comprehensive real-time monitoring of indoor air quality and thermal conditions. Through a unified interface, the sensor connects with residential HVAC systems and transmits multi-dimensional environmental data to the central controller or smart control system, providing a reliable foundation for system operation. In intelligent HVAC systems, the module can automatically trigger fresh air, air conditioning, dehumidification, or purification strategies based on changes in indoor air quality. When CO₂ or PM2.5 concentration rises, TVOC exceeds the threshold, or temperature and humidity move outside the comfort range, the system can automatically adjust airflow, ventilation frequency, or operating mode without manual intervention. Through multi-parameter sensing and coordinated control, it helps improve indoor air health, living comfort, and overall system energy efficiency, meeting modern residential needs for smart and healthy air management.

Key Advantages
