environmental sensor

1.Environmental sensor product introduction

environmental sensor can monitor the environment of negative oxygen ions, pm2.5, pm10, temperature, humidity, air pressure, oxygen content, noise, wind speed, wind direction and other parameters.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 five-element micro-meteorometers, six-element micro-meteorometers, small automatic weather stations and other meteorological products we develop and produce have been widely used in meteorological monitoring, urban environment In the fields of 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.

The environmental sensor innovatively integrates negative oxygen ions, PM2.5, PM10, temperature, humidity, air pressure, oxygen content, noise, wind speed, wind direction and other meteorological elements through a highly integrated structure, which can realize 24-hour continuous outdoor meteorological parameters.Online monitoring, ten parameters are output to the user at one time through the digital communication interface.

2.Environmental sensor product features

1.The ultrasonic probe is hidden in the top cover to avoid interference from rain and snow accumulation and avoid obstruction by natural wind (utility model patent, patent number ZL 2020 2 3215713.X) ☆

2.The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5) ☆

3.Integrated ten elements of negative oxygen ions, pm2.5, pm10, temperature, humidity, air pressure, oxygen content, noise, wind speed and wind direction

4.Adopt advanced sensing technology, real-time measurement, no starting wind speed☆

5.Strong anti-interference ability, with watchdog circuit and automatic reset function to ensure stable operation of the system

6.High integration, no moving parts, zero wear and tear

7.Maintenance-free, no on-site calibration required

8.ASA engineering plastics are used for outdoor applications without discoloration all year round.

9.The standard output signal of product design is RS485 communication interface (MODBUS protocol); optional 232, USB, and Ethernet interfaces support real-time reading of data☆

10.Optional wireless transmission module, minimum transmission interval is 1 minute

11.The probe is a snap-on design, which solves the problem of looseness and inaccurateness during transportation and installation☆
