Multi-factor weather sensor

1. Product Introduction

Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise 　　specializing in R&D, production and sales of micro weather instruments , has been committed to the promotion and application of micro weather instruments and meteorological environment solutions. With a complete production chain, a strong technical team and a comprehensive marketing team, we have developed and produced ultrasonic anemometers , five-element micro-weather instruments, six-element micro-meteorometers and small automatic weather stations and other meteorological products, which have been widely used in Meteorological monitoring, urban environmental monitoring, wind power generation, marine ships, aviation airports, bridges and tunnels, etc., have customers all over the country, and have achieved good social and economic benefits.

　　Compared with traditional miniature weather instruments , our products overcome the need for high-precision timers, and avoid inaccurate measurements caused by sensor start-up delays, demodulation circuit delays, and temperature changes.

The FT-WQX9 nine-element micro-meteorological instrument innovatively realizes the monitoring of ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, rainfall, photoelectric radiation, PM2.5, and PM10 through a highly integrated structure, which can realize outdoor Meteorological parameters are continuously monitored online for 24 hours, and nine parameters are output to the user at one time through the digital communication interface. The product is compact in structure, beautiful in appearance, generous and highly integrated.

2. Product Features

1. The ultrasonic probe is hidden in the top cover, avoiding the interference of rain and snow accumulation, and avoiding natural wind blocking (utility model patent, patent number ZL 2020 2 3215713.X)☆

2. The principle is to transmit continuously variable frequency ultrasonic signals, and detect wind speed and direction by measuring relative phase (invention patent, patent number ZL 2021 1 0237536.5)☆

3. Wind speed, wind direction, temperature, humidity, air pressure, rainfall, photoelectric radiation, PM2.5, PM10 nine elements integrated (utility model patent, patent number ZL 2020 2 3215649.5)☆

4. Using advanced sensing technology, real-time measurement, no start-up wind speed☆

5. Strong anti-interference ability, with watchdog circuit and automatic reset function, to ensure the stable operation of the system

6. High integration, no moving parts, zero wear

7. Maintenance-free, no on-site calibration required

8. Using ASA engineering plastics for outdoor applications does not change color all year round

9. The standard output signal of product design is RS485 communication interface (MODBUS protocol); optional 232, USB, Ethernet interface, support real-time data reading☆

10. Optional wireless transmission module, the minimum transmission interval is 1 minute

11. The probe is a snap-on design, which solves the problem of inaccurate loosening during transportation and installation☆
