28
29 The Dragino (% style="color:blue" %)**Weather Station Kit**(%%) is designed for **measuring atmospheric conditions** to provide information for weather forecasts and to study the weather and climate.
30
31 The Weather Station Kit includes (% style="color:blue" %)**a NB transmitter WSC2-N, a 9 in 1 Weather Station WSS-09 and a Rain Gauge WSS-08**.
32
33 (% style="color:blue" %)**Please note that the WSC2-N only includes the transmitter, and the 9 in 1 Weather Station WSS-09 and Rain Gauge WSS-08 need to be purchased separately.**
34
35 The 9 in 1 weather station kit can measure below values: (% style="color:blue" %)**Wind Speed, Wind Direction, Temperature, Humidity, Air Pressure, Illumination, PM2.5, PM10, Noise & Rain Gauge**(%%).
36
37 The NB transmitter use RS485 interface to communicate with the 9 in 1 weather station. It can also connect (% style="color:blue" %)**3rd party RS485 sensors**(%%) to measure more environment data. It also has a pulse counting input which can be used to connect (% style="color:blue" %)**tipping bucket Rain Gauge**(%%).
38

143
144 (% style="color:red" %)**Notice 1:**
145
146 * All weather sensors and WSC2-N are powered by MPPT solar recharge controller. MPPT is connected to solar panel and storage battery.
147 * Weather sensors won't work if solar panel and storage battery fails.
148
149 (% style="color:red" %)**Notice 2:**
150
151 Due to shipment and importation limitation, user is better to purchase below parts locally:
152
153 * Solar Panel
154 * Storage Battery

158 == 2.2 Send data to IoT server via NB-IoT network ==
159
160
161 (((
162 The WSC2-N is equipped with a NB-IoT module, the pre-loaded firmware in WSC2-N will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module.  The NB-IoT network will forward this value to IoT server via the protocol defined by WSC2-N.

165
166 Below shows the network structure:
167
168 [[image:image-20250113190510-1.png]]
169
170 There are two version: (% style="color:blue" %)**-GE**(%%) and (% style="color:blue" %)**-1T**(%%) version of WSC2-N.
171
172
173 (% style="color:blue" %)**GE Version**(%%): This version doesn't include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set WSC2-N send data to IoT server.
174
175 * Install NB-IoT SIM card and configure APN. See instruction of [[Attach Network>>url:http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.AttachNetwork]].
176
177 * Set up sensor to point to IoT Server. See instruction of [[Configure to Connect Different Servers>>url:http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H3.Configuretoconnecttodifferentservers]].

831 == 8.1 What should I do when the RS485 sensor cannot collect data? ==
832
833
834 ~1. Recheck whether the sensor's power supply voltage is 12V at maximum.
835
836 2. Recheck whether the A and B signal lines of the sensor are connected reversely.
837
838 3. Check whether the sensor's transmission baud rate is 4800. If not, please change it to 4800 and try reading again.

840
841 == 8.2 Why does the weather station make electric current sounds during operation? ==

847 == 8.3 How to solve the problem of temperature difference in weather stations? ==
848
849
850 You can use AT+RSWRITE (downlink: E2 xx xx xx xx xx xx xx ) to modify the temperature compensation function in the weather station.
851
852 **For example：**
853
854 When the temperature of the weather station is 3°C different from the right value, you can use AT+RSWRITE=01 06 00 50 00 1E 09 D3 (downlink: E2 01 06 00 50 00 1E 09 D3) to modify the temperature compensation value of the weather station to +3°C .

856
857 == 8.4 Why does the rain gauge have no data? ==
858
859 The default mode of the rain gauge is trigger mode.
860 When it rains, it will trigger an uplink, and the data does not include rainfall data.
861 If you want to query rainfall data, please change to counting mode
862
863 Feature: Users can set the trigger mode to counting mode or interrupt mode as needed.
