Multi-element 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-WQX10 ten-element micro-meteorological instrument innovatively realizes air temperature, humidity, atmospheric pressure, wind speed, wind direction, PM2.5, PM10, noise, rainfall, and light through a highly integrated structure, which can realize outdoor meteorological parameters 24-hour continuous online monitoring, and output ten parameters to the user at one time through the digital communication interface.

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 emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5) ☆

3. Integrated ten elements of temperature, humidity, atmospheric pressure, wind speed, wind direction, PM2.5, PM10, noise, rainfall, and lighting (utility model patent, patent number ZL 2020 2 3215649.5)☆

4. Adopt advanced sensing technology, real-time measurement, no starting wind speed☆

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

6. High integration, no moving parts, zero wear and tear

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

8. ASA engineering plastics are used for outdoor applications without discoloration all year round.

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

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

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