Miniature weather instrument FT-WQX7

1. Miniature Weather Instrument FT-WQX7 Product Introduction
　　The miniature weather instrument FT-WQX7 can be installed on weather stations, smart street lights, and negative oxygen ion monitoring stations. The miniature weather instrument FT-WQX7 has high measurement accuracy , and has a wide range of applications, and can monitor meteorological elements in real time. 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 micro meteorological instrument FT-WQX7 realizes the seven meteorological standard parameters (ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, rainfall, light/total radiation pass) through a highly integrated structure, which can realize outdoor meteorological parameters for 24 hours Continuous online monitoring, seven parameters are output to the user at one time through the digital communication interface.
