Miniature sensor

1.Miniature sensor product introduction

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.

Compared with traditional micro-meteorological instruments, our products overcome the need for high-precision timers and avoid inaccurate measurements caused by sensor startup delays, demodulation circuit delays, and temperature changes.

Miniature sensor realizes the seven meteorological standard parameters (air temperature, air humidity, wind speed, wind direction, atmospheric pressure, optical rainfall, and light) through a highly integrated structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters and output the seven parameters to users at one time through the digital communication interface.

2. Features of Miniature sensor

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

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

3. Temperature, humidity, wind speed, wind direction, atmospheric pressure, optical rainfall, and illumination are integrated (utility model patent, patent number ZL 2020 2 3215649.5)☆

4. Using advanced sensing technology, real-time measurement, no start-up 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

7. Maintenance-free, no need for on-site calibration

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

9. The product design output signal is standardly equipped with RS485 communication interface (MODBUS protocol); 232, USB, Ethernet interface are optional, supporting real-time data reading☆

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

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