Environmental Monitoring System Enables Automated Monitoring of Wind Speed, Wind Direction, and Air Quality

Serving as a foundational component of environmental observation infrastructure, the Environmental Monitoring System integrates a suite of high-precision sensors to enable the automated monitoring of wind speed, wind direction, and ambient air quality. Typically employing physical principles such as ultrasonic technology and the photoelectric effect, this device provides stable and reliable data support, finding widespread application in fields such as ecological conservation, agro-forestry meteorology, and urban environmental assessment.

Regarding meteorological parameter observation, the device utilizes ultrasonic principles to measure wind speed, covering a range of 0 to 60 meters per second with an accuracy of ±0.1 m/s plus 0.01 times the wind speed value. Wind direction is measured across a full 0 to 360-degree range with an accuracy of ±2 degrees. Air temperature is determined using the diode junction voltage method, covering a range from -40°C to +80°C, with an accuracy of ±0.3°C at 25°C. Air humidity is measured using a capacitive sensor, covering the full range of 0% to 100% relative humidity (RH); within the 20% to 80% RH range, accuracy is better than ±3% RH. Atmospheric pressure is determined via piezoresistive principles, covering a range between 300 and 1100 hectopascals (hPa).

Light intensity is sensed in real-time based on the photoelectric effect, with a measurement ceiling exceeding 157,000 lux and a reading error of less than ±3%. Optical rainfall monitoring employs a photoelectric sensor capable of detecting precipitation intensities ranging from 0 to 4 millimeters per minute, with a measurement error not exceeding ±4%. For particulate matter concentration monitoring, the device utilizes light scattering principles to measure both PM2.5 and PM10; both parameters share a measurement range of 0 to 1000 micrograms per cubic meter (µg/m³), with an accuracy of ±10% for measured values below 500 µg/m³. Furthermore, noise monitoring is conducted using a capacitive microphone capable of sensing sound pressure levels ranging from 30 to 120 decibels (dB), with a resolution of 0.1 dB.

By highly integrating this diverse array of sensors, the Environmental Monitoring System achieves the simultaneous, real-time observation of multiple environmental parameters, thereby effectively enhancing both the efficiency and accuracy of environmental monitoring operations.
