    FAQ
    ❯
    • 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.

    ❯
    • 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.
    ❯

    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.

    Perfect for Industrial Use
    I installed this sensor at a construction site to track dust and pollution levels. It provides reliable readings and integrates easily with our monitoring system via 4-20mA and 0-10V outputs. Very durable and built to withstand tough outdoor conditions.
