Negative ion sensor

1.Negative ion sensor product introduction

Negative ion sensor collects and measures the number of negative oxygen ions in the air, which can be monitored for 24 hours and used to evaluate the quality of the air.Shandong Fengtu Internet of Things Technology Co., Ltd., as a company specializing in the 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 developed and produced, such as the five-element micro-meteorological instrument, the six-element micro-meteorological instrument and the small automatic weather station, 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 negative ion sensor innovatively realizes meteorological elements such as negative oxygen ions, air temperature, humidity, PM2.5, PM10, etc. through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters and output the five parameters to the user at one time through the digital communication interface.
