All-in-One Air Quality Sensor (PM + CO₂ + Temperature & Humidity + Optional AQS)
Integrated multi-parameter sensing for more accurate and intelligent HVAC control
The all-in-one air quality sensor integrates PM2.5, CO₂, temperature, humidity, and optional AQS into a single module, enabling coordinated multi-parameter monitoring through a unified structure and algorithm. The module combines optical scattering for PM detection, automotive-grade NDIR for CO₂ sensing, and a high-precision temperature and humidity chip, with optional MOx-based AQS for detecting external pollutant gases. Multi-dimensional data fusion allows more accurate evaluation of cabin air quality trends. Real-time data can be transmitted to the HVAC system for automatic control of fresh and recirculation modes, fan speed, and air purification functions. In traffic congestion, multi-passenger conditions, tunnels, and exhaust-heavy environments, the system can actively adjust air management strategies based on sensor data to help maintain a healthy cabin environment. With high integration, strong consistency, and reliable performance, the module helps reduce vehicle packaging complexity, wiring, and interface costs while improving overall air quality management for a smarter, healthier, and more energy-efficient cabin.
Key Advantages
High Integration
Integrates PM2.5, CO₂, temperature, humidity, and optional AQS in one module, reducing sensor count, wiring, and installation cost.
High Consistency
All sensing elements are calibrated under a unified in-house system to ensure stable cross-batch and cross-temperature performance for vehicle integration.
Automotive-Grade
Designed for stable operation under -40°C to 85°C, high humidity, vibration, and dusty conditions, with temperature compensation for long-term reliability.
Compact Design
The all-in-one architecture reduces ECU interface demand, installation space, and harness complexity, improving system-level cost efficiency.
All-in-One Sensor Series
The all-in-one air quality sensor combines PM2.5, CO₂, AQS (VOC/NO₂/NH₃/CO), and temperature and humidity sensing to provide comprehensive real-time monitoring of in-cabin and external air conditions. Multi-dimensional air data is transmitted to the vehicle system and displayed digitally, allowing drivers to monitor cabin air quality at a glance. Based on sensor input, the HVAC system can automatically switch between fresh and recirculation modes, enhance purification performance, or adjust airflow to maintain a safe, clean, and comfortable cabin environment. The all-in-one design replaces multiple standalone sensors, significantly reducing system complexity and overall cost while improving consistency and reliability. Whether in urban traffic, tunnels, exhaust-heavy areas, or on long-distance journeys, the system supports continuous air quality management to help reduce pollution exposure and create a safer and healthier travel experience.
