1.  Introduction

1.1  Overview

Dragino LoRaWAN weather station series products are designed for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. They consist of a main process device (WSC1-L) and various sensors.

The sensors include various type such as: Rain Gauge, Temperature/Humidity/Pressure sensor, Wind Speed/direction sensor, Illumination sensor, CO2 sensor, Rain/Snow sensor, PM2.5/10 sensor, PAR(Photosynthetically Available Radiation) sensor, Total Solar Radiation sensor and so on.

Main process device WSC1-L is an outdoor LoRaWAN RS485 end node. It is powered by external 12v solar power and have a built-in li-on backup battery. WSC1-L reads value from various sensors and upload these sensor data to IoT server via LoRaWAN wireless protocol.

WSC1-L is full compatible with LoRaWAN Class C protocol, it can work with standard LoRaWAN gateway.

2.  How to use

2.1  Installation

Below is an installation example for the weather station. Field installation example can be found at Appendix I: Field Installation Photo.  



1. WSC1-L and sensors all powered by solar power via MPPT

2. WSC1-L and sensors connect to each other via RS485/Modbus.

3. WSC1-L read value from each sensor and send uplink via LoRaWAN

WSC1-L is shipped with a RS485 converter board, for the easy connection to different sensors and WSC1-L. Below is a connection photo:


Notice 1:

  • All weather sensors and WSC1-L are powered by MPPT solar recharge controller. MPPT is connected to solar panel and storage battery.
  • WSC1-L has an extra 1000mAh back up battery. So it can work even solar panel and storage battery Fails.
  • Weather sensors won't work if solar panel and storage battery fails.

Notice 2:

Due to shipment and importation limitation, user is better to purchase below parts locally:

  • Solar Panel
  • Storage Battery
  • MPPT Solar Recharger
  • Mounting Kit includes pole and mast assembly. Each weather sensor has it's own mounting assembly, user can check the sensor section in this manual.
  • Cabinet.

2.2  How it works?

Each WSC1-L is shipped with a worldwide unique set of OTAA keys. To use WSC1-L in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After finish installation as above. Create WSC1-L in your LoRaWAN server and Power on WSC1-L , it can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

Open WSC1-L and put the yellow jumper as below position to power on WSC1-L.



  1. WSC1-L will auto scan available weather sensors when power on or reboot.
  2. User can send a downlink command to WSC1-L to do a re-scan on the available sensors.

2.3  Example to use for LoRaWAN network

This section shows an example for how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.


Assume the DLOS8 is already set to connect to TTN V3 network . We need to add the WSC1-L device in TTN V3:

Step 1: Create a device in TTN V3 with the OTAA keys from WSC1-L.

Each WSC1-L is shipped with a sticker with the default device EUI as below:


User can enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:

Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).


Add APP EUI in the application.



Choose Manually to add WSC1-L




Step 2: Power on WSC1-L, it will start to join TTN server. After join success, it will start to upload sensor data to TTN V3 and user can see in the panel.


2.4  Uplink Payload

Uplink payloads include two types: Valid Sensor Value and other status / control command.

  • Valid Sensor Value: Use FPORT=2
  • Other control command: Use FPORT other than 2.

2.4.1  Uplink FPORT=5, Device Status

Uplink the device configures with FPORT=5. Once WSC1-L Joined the network, it will uplink this message to the server. After first uplink, WSC1-L will uplink Device Status every 12 hours

User can also use downlink command(0x2301) to ask WSC1-L to resend this uplink

6.6  Total Solar Radiation sensor -- WSS-06

WSS-06 is Total Radiation Sensor can be used to measure the total solar radiation in the spectral range of 0.3 to 3 μm (300 to 3000 nm). If the sensor face is down, the reflected radiation can be measured, and the shading ring can also be used to measure the scattered radiation.

The core device of the radiation sensor is a high-precision photosensitive element, which has good stability and high precision; at the same time, a precision-machined PTTE radiation cover is installed outside the sensing element, which effectively prevents environmental factors from affecting its performance

WSS-06 is designed to support the Dragino Weather station solution.  Users only need to connect WSS-06 RS485 interface to WSC1-L. The weather station main processor WSC1-L can detect and upload Total Solar Radiation to the IoT Server via wireless LoRaWAN protocol.

4:Current Hourly rainfall: etc 0.2mm

5:Rainfall in last hour: etc 0.2mm

6:24-hour maximum rainfall: etc  10.0mm

8:24-hour minimum rainfall: etc  0.0mm

10:Rainfall in 24 hours: 8.0mm   (Rainfall in the last 24 hours)

8.  Trouble Shooting

8.1  AT Command input doesn't work

In the case if user can see the console output but can't type input to the device. Please check if you already include the ENTER while sending out the command. Some serial tool doesn't send ENTER while press the send key, user need to add ENTER in their string. 

8.2  Possible reasons why the device is unresponsive:

1. Check whether the battery voltage is lower than 2.8V
2. Check whether the jumper of the device is correctly connected


3. Check whether the switch here of the device is at the ISP(The switch can operate normally only when it is in RUN)
