Piezoelectric sensor

1.Piezoelectric 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.

The FT-Y12 12-element micro-meteorological instrument, also known as the atmospheric pollution environment monitor, is a highly integrated instrument developed by Shandong Fengtu Internet of Things Technology Co., Ltd. to monitor 12 parameters, including six pollutant parameters of PM2.5, PM10, CO, SO2, NO2, and O3, as well as air temperature, relative humidity, wind speed, wind direction, atmospheric pressure, and piezoelectric rainfall, in response to the increasingly severe environmental situation. Its main function is to monitor conventional pollution factors and meteorological auxiliary parameters in the air online for 24 hours, 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. can be optionally equipped.

The FT-Y12 air pollution environment monitor can be used in urban grid environment monitoring and control, smart street lights, scenic area environment monitoring, factories or mines, construction sites (construction site dust monitoring), urban roads, highways, public places and other places involving air quality monitoring.

2. Features of Piezoelectric sensor

1. The top cover hides the ultrasonic probe 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 continuous frequency-variable ultrasonic signal and detect wind speed and direction by measuring the relative phase (invention patent, patent number ZL 2021 1 0237536.5)☆

3. PM2.5, PM10, CO, SO2, NO2, O3, temperature, humidity, wind speed, wind direction, atmospheric pressure, piezoelectric rainfall twelve elements integrated (utility model patent, patent number ZL 2020 2 3215649.5)☆

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