Dual-signal parallel output: Simultaneously acquires VOC Index + NOx Index (0-500 scale) per sample, response time <1 second
Application Scenarios:
Smart In-Vehicle Systems
Real-time Monitoring:
Excessive formaldehyde (VOC) in cabin
Tunnel exhaust accumulation (NOx) → Automatic switch to internal circulation
Industrial safety alerts
Dual-gas collaborative detection:
Diesel generator leaks (NOx↑ + VOC↑) vs. Alcohol disinfection (VOC↑ only)
Urban microclimate stations
Grid-based deployment for traffic pollution dispersion monitoring (NOx heatmap generation)
