1. Product Introduction

The air quality sensor is a device that can monitor real-time wind speed, direction, temperature, humidity, and air pressure in the environment pm2.5、pm10、 Sensor equipment for meteorological parameters such as noise, made of ASA engineering plastic, and used for outdoor applications with constant color throughout the year

As a professional manufacturer of micro-meteorological instruments, our company has been committed to the research, development, production and sales of micro-meteorological instruments and meteorological environmental solutions. With a complete production chain, a strong technical team and a comprehensive marketing team, we have developed and produced meteorological products such as ultrasonic anemometers, five-element micro-meteorological instruments, six-element micro-meteorological instruments and small automatic meteorological stations, which have been widely used in meteorological monitoring, urban environmental monitoring, wind power generation, navigation ships, civil aviation airports, bridges and tunnels and other fields. Our customers are spread all over the country and have achieved good social and economic benefits.

Compared with traditional micro-meteorological instruments, our company's products overcome the need for high-precision timing devices, avoiding the problems of inaccurate measurement caused by sensor startup delay, demodulation circuit delay, and temperature changes.

The WQX8 type of eight-element micro-meteorological instrument innovatively integrates meteorological standard parameters (wind speed, wind direction, temperature, humidity, atmospheric pressure, pm2.5, pm10, noise) through a highly integrated structure to achieve, which can continuously monitor outdoor meteorological parameters online for 24 hours, and output the eight parameters to the user at one time through a digital communication interface. The product structure is compact, the appearance is beautiful, generous, and highly integrated.

2. Product features
