20
21
22 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.
23
24 The Weather Station Kit includes (% style="color:blue" %)**a LoRaWAN transmitter WSC3-L, an interrupting rain gauge and a 3-in-1 sensor and a light sensor.**
25
26 (% style="color:blue" %)**Please note that the WSC3-L only includes the transmitter, the 3-in-1 sensor and the interrupting rain gauge and light sensor need to be purchased separately.**
27
28 The 3-in-1 sensor can measure the following values: (% style="color:blue" %)**Temperature, Humidity, Air pressure.**
29
30 The LoRaWAN transmitter uses an I2C interface to communicate with the weather station sensor. It also has a pulse count input that can be used to connect a (% style="color:blue" %)**tipping bucket Rain Gauge**(%%).
31
32 WSC3-L is full compatible with LoRaWAN Class A protocol, it can work with standard LoRaWAN gateway.

433 The WSC3-L uses OTAA mode and below frequency plans by default. Each frequency band use different firmware, user update the firmware to the corresponding band for their country.

440 == 3.1 Configure Methods ==
441
442
443 WSC3-L supports below configure method:
444
445 * AT Command via Bluetooth Connection (**Recommended**): [[BLE Configure Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/BLE%20Bluetooth%20Remote%20Configure/]].
446
447 * AT Command via UART Connection : See [[UART Connection>>http://wiki.dragino.com/xwiki/bin/view/Main/UART%20Access%20for%20LoRa%20ST%20v4%20base%20model/#H2.3UARTConnectionforSN50v3basemotherboard]].
448
449 * LoRaWAN Downlink.  Instruction for different platforms: See [[IoT LoRaWAN Server>>http://wiki.dragino.com/xwiki/bin/view/Main/]] section.
450
451 == 3.2 Serial Access Password ==
452
453 After the Bluetooth or UART connection is successful, use the Serial Access Password to enter the AT command window.
454
455 The label on the box of the node will print the initial password: AT+PIN=**xxxxxx**, and directly use the six-digit password to access the AT instruction window.
