weather sensor

1.Weather sensor product introduction

Shandong Fengtu Internet of Things Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales 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 meters, five-element micrometeorometers, six-element micrometeorometers and small automatic weather stations have been widely used in In the fields of meteorological monitoring, urban environment monitoring, wind power generation, navigation ships, aviation airports, bridges and tunnels, etc., we 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 measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

The weather sensor, also called the air pollution environment monitor, was developed by Shandong Fengtu Internet of Things Technology Co., Ltd.in response to the increasingly severe environmental protection situation.A highly integrated instrument that monitors a total of 12 parameters including temperature, air humidity, wind speed, wind direction, atmospheric pressure and optical rainfall.The main function is to conduct 24-hour continuous online monitoring of conventional pollution factors and meteorological auxiliary parameters in the air, and provide the analyzed data to the Environmental Protection Bureau as a reference for air quality and to assist in environmental protection decision-making.In addition, hydrogen sulfide, volatile organic pollutants, solar radiation, noise, etc.are optional.

The weather sensor can be applied to urban grid environmental monitoring and control, smart street lights, scenic area environmental monitoring, factories or mines, construction sites (construction site dust monitoring), urban roads, highways, public places and other places involving air quality monitoring.
