Miniature sensor

1.Introduction to Miniature sensor products

Miniature sensor is used to measure meteorological parameters in the environment. It integrates multiple parameters into one and can measure a variety of environmental factors.Shandong Fengtu IoT Technology Co., Ltd., as an enterprise specializing in the research, development, production and sales of micro meteoroscopes, has always been committed to the promotion and application of micro meteoroscopes and meteorological environment solutions.With a complete production chain, strong technical team and comprehensive marketing team, we have developed and produced meteorological products such as ultrasonic wind speed wind meter, five-element micrometeoroscope, six-element micrometeoroscope and small automatic weather station, which have been widely used in In the fields of meteorological monitoring, urban environmental monitoring, wind power generation, navigation and ships, aviation airports, bridges and tunnels, customers are spread all over the country and have achieved good social and economic benefits.

Compared with traditional micro meteoroscopes, our products overcome the demand for high-precision timers and avoid inaccurate measurement problems caused by sensor startup delay, demodulation circuit delay, and temperature changes.

Miniature sensor implements the seven meteorological parameters (air temperature, air humidity, wind speed, wind direction, atmospheric pressure, optical rainfall, light) through a high-integration structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters through digital communication interface Output seven parameters to the user at one time.

2.Miniature sensor product features

1.The hidden ultrasonic probe on the top cover avoids interference from rain and snow accumulation and avoids natural wind shading (Utility model patent, patent number ZL 2020 2 3215713.X)☆

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