1. This Sensor with Ambient Temperature and Relative Humidity integrated, is installed in a three-layer outdoor radiation shield.

The radiation shield adopts PC+ fiber special proportion configurataion, and the interior is sprayed with thermal insulation

layer, to minimize the solar radiation influence.

2. Supplementary Description on Wind Speed, Wind Direction: The wind speed and wind direction is measured through ultrasonic

principle.

3. Optical Rainfall: automatically senses rain falling on its outer surface and calcultes the amount of rainfall according to the

size and number of raindrops. Compare with the traditional physical bucket rain gauge, the accuracy of the optical rain gauge is

its weakness. Most of the time, the reading of the optical rain gauge will be close to the bucket rain gauge, but abnormal events

will be significantly different (heavy rain). But it is an integrated design, more suitable for application in site where tipping

bucket rainfall is hard to apply, not restried by the installation situation. And when the rainfall is small and light, it is more

sensitive.

4. Noise: Select high precision electret pickup, A weighting method to meaure environmental noise. It is small in volume, high

precision and high sensitivity.

5. PM2.5/PM10 Particular Matter: Based on the principle of laser scattering, the number of suspended particulate matter with

different particle sizes in the air in a unit volume can be continuously collected and calculated, that is, the conentration

distribution of particulate matter.

6. Illuminance/ Solar Radiation (Either-or): Select optical components of different specifications and special filters to measure

illumination and solar radiation data.

7. XF_PcSoftV1.0: the upper computer reading software, Nong-IoT developed for XF series compact weather station.
