R68 is a highly integrated instrument developed for the smart lamp pole industry, which monitors eight parameters including atmospheric temperature, humidity, wind speed, wind direction, illumination, noise, PM2.5 and PM10. It can realize 24-hour continuous online monitoring of outdoor meteorological parameters, and output all parameters to users at one time through digital communication interface.
Air quality monitoring micro station can be applied to urban grid environmental monitoring and control, intelligent street lamps, scenic area environmental monitoring, factories or mines, construction sites (site dust monitoring), urban roads, highways, public places and other places related to air quality monitoring.

Note: Arrow indicating location
When installing the device, the arrow of the positioning indicator marked on the device should point to the north direction. The value of north of the device is 0°, increasing clockwise. 90 degrees is east. Electronic compasses do not require pointing north installation.
It is best to use a device with magnetic deflection correction when looking north, or if not, adjust it according to the latitude and longitude of the device installed.
When selecting an installation position, observe the following principles:
1. Ensure that there is no ultrasonic equipment of the same type around to avoid mutual interference;
2. The installation site should be open land, downwind side;
3. The installation height should not be less than 1.5m, and the installation distance from the nearest obstacle should be more than 10 times the height of the brick building;
4. If radiation parameters are included, it should be installed in an open field; The whole height Angle range is from sunrise to sunset, and the elevation Angle of obstacles within the range is no more than 5° without any shadow falling on the sensor, avoiding thermal radiation, steam and bright color buildings.
