Features
- Ultrasonic probe hidden in the top cover to avoid the interference of rain and snow accumulation and avoid the obstruction of natural wind
- The principle is to transmit a continuous frequency conversion ultrasonic signal, and detect the wind speed and direction by measuring the relative phase.
- PM2.5, PM10, CO, SO2, NO2, O3, temperature, humidity, wind speed, wind direction, atmospheric pressure, rainfall twelve elements integrated
- Adopt advanced sensor technology, real-time measurement, no starting wind speed
- Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system
- High integration, no moving parts, zero wear
- Maintenance-free, no on-site calibration
- Adopting ASA engineering plastics for outdoor applications, does not change color all year round
- The standard configuration of product design output signal is RS485 communication interface (MODBUS protocol); optional 232, USB, Ethernet interface, support real-time data reading
- Optional wireless transmission module, the minimum transmission interval is 1 minute
- The probe is a snap-in design, which solves the problem of inaccurate looseness during transportation and installation
