Vehicle Meteorological Sensor(VMS)

1.Introduction to Vehicle Meteorological Sensor(VMS) Products

Vehicle Meteorological Sensor(VMS) is a meteorological sensor for ground vehicles used by first responders, firefighters, and Hazmat teams.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 a 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 meteorological station.They have been widely used in meteorological monitoring, urban environment monitoring, wind power generation, navigation and ships, aviation airports, bridges and tunnels, etc.We have customers all over the country and have achieved good social and economic benefits.

The principle of Vehicle Meteorological Sensor(VMS) is to transmit continuous frequency conversion ultrasonic signals, and to detect wind speed and direction by measuring relative phase.Compared with traditional ultrasonic wind speed and directional instruments, 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.

Vehicle Meteorological Sensor(VMS) innovatively implements the six meteorological parameters (ambient temperature, relative humidity, wind speed, wind direction, atmospheric pressure, piezoelectric rainfall) through a high-integration structure, which can realize 24-hour continuous online monitoring of outdoor meteorological parameters, and output six parameters to users at one time through the digital communication interface.
