What is LWL02 LoRaWAN Water Leak Sensor 25 25 26 - ==Sub-paragraph==17 +The Dragino LWL02 is a LoRaWAN Water Sensor. When there is water between the two metal probes, LWL02 indicates a water leak event and uplink to IoT server via LoRaWAN network. 27 27 28 -Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. 29 29 30 - ==Sub-paragraph==20 +LWL02 is powered by 2 x AAA batteries and target for long time use, these two batteries can provide about 16,000 ~~ 70,000 uplink packets, which result in 2 ~~ 10 years battery life. After battery running out, user can easily open the enclosure and replace with 2 common AAA batteries. 31 31 32 -Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum. 22 + 23 +The LWL02 will send periodically data every day as well as for each water leak event. It also counts the water leak times and calculate last water leak duration. User can also disable the uplink for each water leak event, instead, device can count each event and uplink periodically. 24 + 25 + 26 +Each LWL02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to 27 + 28 +LoRaWAN server and it will auto connect after power on.

How to install LWL02 79 + 80 +When install the LWL02 on wall. Please install as below so the water leak probe will be soak in water for water detect purpose. The LWL02 main body is not water proof. Please don’t let water go inside the LWL02 main body. 81 + 82 + 83 +|((( 84 +50cm 85 + 86 + 87 +))) 88 + 89 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image005.png]] 90 + 91 + 92 + 93 + 94 + 95 + 96 +1. Operation Mode 97 +11. How it works? 98 + 99 +The LWL02 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join network. To connect a local LoRaWAN network, user just need to input the OTAA keys in the network server and [[power on>>path:#Power_on]] the LWL02. It will auto join the network via OTAA. 100 + 101 + 102 +In case user can’t set the OTAA keys in the network server and has to use the existing keys from server. User can [[use AT Command>>path:#AT_Command]] to set the keys in the devices. 103 + 104 + 105 +1. 106 +11. Example to join LoRaWAN network 107 + 108 +Here shows an example for how to join the [[TTN V3 Network>>url:https://eu1.cloud.thethings.network/]]. Below is the network structure, we use [[LG308>>url:http://www.dragino.com/products/lora-lorawan-gateway/item/140-lg308.html]] as LoRaWAN gateway here. 109 + 110 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image006.png]] 111 + 112 + 113 + 114 +The LWL02 has water leak detect probe as above. When there is water between these two detect probe, they will be short and generate the water leak event. and send the status to LoRaWAN server. The LWL02 will uplink two type of messages to the server. 115 + 116 +* A keep-alive message which send once per day. 117 +* An emergency event message when detect a water leak. ([[Alarm event can be disabled>>path:#Alarm]]) 118 +* A periodically update at every 10 minutes when in water leak. 119 +* A message when switch from water leak to none water leak. ([[Alarm event can be disabled>>path:#Alarm]]) 120 + 121 + 122 +The LG308 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. What we need to now is only configure the TTN V3: 123 + 124 +**Step 1**: Create a device in TTN V3 with the OTAA keys from LWL02. 125 + 126 +Each LWL02 is shipped with a sticker with unique device EUI: 127 + 128 +[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image007.png]] 129 + 130 + 131 + 132 + 133 +User can enter this key in their LoRaWAN Server portal.
