micro weather sensor

1.Micro weather sensor product introduction

micro weather sensor is a small sensor that measures multi-element weather elements, specifically designed to measure and monitor meteorological data in the environment.Shandong Fengtu Internet of Things Technology Co., Ltd., as a company specializing in the development, production and sale of micro-meteorological instruments, has been committed to the promotion and application of micro-meteorological instruments and meteorological environment solutions. With a complete production chain, a strong technical team and a comprehensive marketing team, the meteorological products we develop and produce, such as ultrasonic wind speed and direction instruments, five-element micro-meteorological instruments, six-element micro-meteorological instruments and small automatic weather stations, have been widely used in meteorological monitoring, urban environmental monitoring, wind power generation, marine vessels, aviation airports, bridges and tunnels, etc., with customers all over the country, and have achieved good social and economic benefits.

The principle of micro weather sensor is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring relative phase. Compared with traditional ultrasonic anemometers, our products overcome the need for high-precision timers and avoid inaccurate measurements caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The micro weather sensor innovatively implements the six meteorological standard parameters (ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and optical rainfall) through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters and output the six parameters to the user at one time through the digital communication interface.
