60

61

62

(% style="color:blue" %)** Wiring:**

63

64

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

65

66

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

67

68

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

69

70

71

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

74

75

76

(% style="color:red" %) ** Notice 1:**

77

78

* All weather sensors and WSC1-L are powered by MPPT solar recharge controller. MPPT is connected to solar panel and storage battery.

79

* WSC1-L has an extra 1000mAh back up battery. So it can work even solar panel and storage battery Fails.

80

* Weather sensors won’t work if solar panel and storage battery fails.

(% style="color:red" %)** Notice 2:**

86

87

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

* Solar Panel

* Storage Battery

* MPPT Solar Recharger

92

* 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.

93

* Cabinet.

94

95

== 2.2 How it works? ==

96

97

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.

98

99

100

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

101

102

[[image:1656042192857-709.png]]

103

104

105

(% style="color:red" %)**Notice:**

106

107

1. WSC1-L will auto scan available weather sensors when power on or reboot.

108

1. 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 ==

114

115

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.

116

117

118

[[image:1656042612899-422.png]]

Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the WSC1-L device in TTN V3:

123

124

125

(% style="color:blue" %)**Step 1**(%%): Create a device in TTN V3 with the OTAA keys from WSC1-L.

126

127

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

128

129

[[image:image-20220624115043-1.jpeg]]

130

131

132

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

133

134

**Add APP EUI in the application.**

**Add APP KEY and DEV EUI**

150

151

[[image:1656042723199-746.png]]

(% style="color:blue" %)**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 ==

163

164

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

165

166

* Valid Sensor Value: Use FPORT=2

167

* Other control command: Use FPORT other than 2.

=== 2.4.1 Uplink FPORT~=5, Device Status ===

173

174

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

175

176

177

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

WSC1-L will send this uplink after Device Config uplink once join LoRaWAN network successfully. And it will periodically send this uplink. Default interval is 20 minutes and [[can be changed>>||anchor="H"]].

282

283

Uplink uses FPORT=2 and every 20 minutes send one uplink by default.

284

== 2.5 Show data on Application Server ==

420

421

Application platform provides a human friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:

422

423

424

(% style="color:blue" %)**Step 1**(%%): Be sure that your device is programmed and properly connected to the LoRaWAN network.

425

426

(% style="color:blue" %)**Step 2**(%%): Configure your Application to forward data to Datacake you will need to add integration. Go to TTN V3 Console ~-~-> Applications ~-~-> Integrations ~-~-> Add Integrations.

458

* (% style="color:#4472c4" %)**General Commands**.

459

460

These commands are to configure:

461

462

* timeout: RS485 receive timeout (uint:ms). Device will close receive window after timeout

Example:

User need to change external sensor use the type code as address code.

541

542

With a 485 sensor, after correctly changing the address code to A1, the RS485 query frame is shown in the following table:

543

544

545

|0xA1|0x03|0x00|0x00|0x00|0x01|0x9C|0xAA

546

| | | | | | | |

547

548

The response frame of the sensor is as follows:

549

550

551

|0xA1|0x03|0x00|0x02|0x00|0x0A|0x7C|0xAD

552

| | | | | | | |

553

554

Then the following parameters should be:

555

556

* Address_Code range: A1

557

* Query_Length: 8

558

* Query_Command: A103000000019CAA

559

* Read_Length: 8

560

* Valid_Data: 24 (Indicates that the data length is 2 bytes, starting from the 4th byte)

561

* has_CRC: 1

562

* timeout: 1500 (Fill in the test according to the actual situation)

563

564

So the input command is:

565

566

AT+DYSENSOR=A1,8,A103000000019CAA,8,24,1,1500

567

568

569

In every sampling. WSC1-L will auto append the sensor segment as per this structure and uplink.

The tipping bucket of WSS-01 is adjusted to the best angle. When installation, user only needs

789

790

to screw up and adjust the bottom horizontally.

791

== 6.6 Total Solar Radiation sensor ~-~- WSS-06 ==

1116

1117

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.

1118

1119

1120

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

1121

1122

1123

WSS-06 is designed to support the Dragino Weather station solution.

1124

1125

1126

Users only need to connect WSS-06 RS485 interface to WSC1-L. The weather station main

== 6.7 PAR (Photosynthetically Available Radiation) ~-~- WSS-07 ==

1173

1174

WSS-07 photosynthetically active radiation sensor is mainly used to measure the photosynthetically active radiation of natural light in the wavelength range of 400-700nm.

1175

1176

1177

WSS-07 use precision optical detectors and has an optical filter of 400-700nm, when natural light is irradiated, a voltage signal proportional to the intensity of the incident radiation is generated, and its luminous flux density is proportional to the cosine of the direct angle of the incident light.

WSS-07 is designed to support the Dragino Weather station solution.
