The working principle and application of ultrasonic weather station

1、 Product Introduction

JD-CQX7 Ultrasonic Meteorological Station is a highly integrated, low-power, quickly installable, and convenient high-precision automatic meteorological observation equipment for field monitoring.

This device is debugging free and can be quickly deployed. It is widely used in fields such as meteorology, agriculture, forestry, environmental protection, oceanography, airports, ports, scientific research, and campus education.

Compared with traditional ultrasonic weather stations, our products overcome the need for high-precision timers and avoid measurement inaccuracies caused by sensor startup delays, demodulation circuit delays, and temperature changes.

This device innovatively adopts a seven element integrated sensor, which can observe meteorological elements such as wind speed, wind direction, temperature, humidity, air pressure, lighting, and optical rainfall in real time. It can achieve 24-hour continuous online monitoring of outdoor meteorological parameters, and output the seven parameters to the user at once through a digital communication interface.

2、 Product Features

1. Hidden ultrasonic probe on the top cover to avoid interference from accumulated rain and snow, and to prevent natural wind obstruction

2. The principle is to emit continuous variable frequency ultrasonic signals and detect wind speed and direction by measuring relative phase
