FAQ

Q1: What are the advantages of SUCH outdoor air quality sensor when deployed on a wide urban scale? ❯

Flexible deployment: compact size, supports solar power supply, easy to install
Real-time networking: WiFi output for centralized data management and early warning
Controllable cost: more cost-effective compared to larger site monitoring systems

These advantages make it very suitable for grid monitoring layout or building urban air quality heat map system.

Q2: What is the difference between analog and WiFi output? ❯

Analog output provides a continuous voltage or current signal (e.g., 0–5V, 4–20mA), ideal for integration with PLCs, industrial controllers, or data loggers.
WiFi output enables wireless data transmission to cloud platforms, mobile apps, or web dashboards, making it suitable for smart city projects or remote environmental monitoring.

Q3: What is the maximum distance for analog signal transmission? ❯

This depends on the type of output and cable specification:

Voltage signals (e.g. 0-5V) Short transmission distance, usually less than 20 meters
Current signals (e.g. 4-20mA) are highly resistant to interference, up to 100 meters or more.
