Description

Overview:
This all-in-one weather station can be widely used in environmental detection, integrating wind speed, wind direction, temperature and humidity, noise collection, PM2.5 and PM10, atmospheric pressure, and light.

Features:

This product is small in size and light in weight. It is made of high-quality anti-ultraviolet materials and has a long service life. It uses a high-sensitivity probe with stable signal and high accuracy. The key components adopt imported components, which are stable and reliable, and have the characteristics of wide measurement range, good linearity, good waterproof performance, convenient use, easy installation, and long transmission distance.

  • It adopts an integrated design with multiple collection devices and is easy to install.
  • Wind speed and direction are measured by ultrasonic principle, no start-up wind speed limit, zero wind speed work, no angle limit, 360° omni-directional, wind speed and wind direction data can be obtained at the same time.
  • Noise collection, accurate measurement, the range is as high as 30dB~120dB.PM2.5 and PM10
  • Simultaneous acquisition, range: 0-1000ug/m3, resolution 1ug/m3, unique dual-frequency data acquisition and automatic calibration technology, consistency can reach ±10%.
  • Measuring the environmental temperature and humidity, the measuring unit is imported from Switzerland, and the measurement is accurate.
  • Wide range 0-120Kpa air pressure range, applicable to various altitudes.
  • Use dedicated 485 circuit, stable communication.
  • Equipment with built-in electronic compass, no direction requirements during installation, horizontal installation.
