LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread
spectrum (CSS) technology. Semtech's LoRa devices and wireless radio frequency technology is a long
range, low power wireless platform that has become the de facto technology for Internet of Things (IoT)
networks worldwide.
1 INTRODUCTION
1.1 What's LoRa
1.2 About Custos WWD
Custos Wireless Water Detector “Custos WWD” detects Water Leakage with long battery operation
lifespan, super tiny form factor detects water from either in body detection probe on 4 sides as well as
optional remote wired water detection probe. It is a perfect companion for Custos BVS to work in concerto
as a complete solution to close water valve once WWD detected water leak (need proper set up on App or
gateway conguration).

-End-user can use built-in 3-axis Accelerometer to replace physical touchable key. it can detect any
movement very sensitive, end-user use a series of action to enable some dened function, such as
below functions
i.To wake up Gustos WWD from sleep mode and send out uplink packet to Gateway / LoRa Server,
ii.Factory Default Reset,
-Custos WWD only support below gesture movement, shake it vertically or horizontally as below

8 HOW WATER LEAK SENSOR WORKS
8.1 Water Detection Probes
8.2 Built-in Water Detection Probes
Custos WWD supports two water detection probe: “Build-in” & “Remote”
9
Figure 8A Figure 8B Figure 8C
Built-in Water Detection Probe
WWD has special recess (Figure 8A) which helps induce Water run through it, to create effective
detection by probes from both ends.
To achieve better result, please lay the WWD at on the oor.
8.3 Removable Water Detection Probe
To ensure the sensor probe works properly, as shown in the picture below (Figure 8B) , please ensure
that the removed sensor probe is inserted tightly and no gap is allowed (Figure 8C) between the 3.5mm
jack and housing.

10
Figure 9A
-By default, Custos WWD is set in Shipping Mode to keep it in deep sleep to save power during
transport & storage, in this time all functions will be disabled until unlocked it from Shipping Mode. End-
user must activate the device from Shipping Mode before joined to any LoRaWAN Network.
-To exit Shipping mode, the user needs to trigger the device's water leak sensor and holds it for at least
2 seconds.
9.2 Standalone Mode
-If Custos WWD is not paired to any LoRa Network and it unlocked from Shipping Mode.
9.3 Network Mode
-Custos WWD is paired with a LoRaWAN Network.
-Supported function as Water Leak Report, Temperature Report, and downlink conguration.

LoRa Network then it will return to shipping mode, this keeps lowers power
consumption.
i.Trigger Built-in Water Leak Sensor for 2 seconds comes with Yellow LED Lights on
per second.
ii.OTAA will be started per 30 seconds automatically if it's remained in standalone
mode.
iii.OTAA success with LoRa Server, 2 Buzzer Sounds and Green LED on when OTAA
success,
iv.After 3 minutes time-out without OTAA success then it will be back to shipping
mode.
10.2 OTAA Activation
-Custos LoRa WWD can support two methods to activate OTAA (time limit mode and forever mode)
i.Periodically activate OTAA for 2 minutes only.
ii.Activate OTAA forever.
10.2.1 Time Limits Activate OTAA

WWDLWx User Manual Date: 19-Apr-2023
Version: 0.2.0
10.2.2 Activate OTAA &Exits Shipping Mode Permanently (Not Recommended)
12
-OTAA will be activated forever until it joined into a LoRaWAN Network, and it will not return to
shipping mode anymore,
i.Trigger Built-in Water Leak Sensor for 5 seconds and comes with Yellow LED Lights on per
seconds.
ii.OTAA will be started per 30 seconds automatically if it's remained in standalone mode.
iii.Yellow LED will keep ashing when OTAA is process with LoRa Server and 2 Buzzer Sounds
and Green LEED on when OTAA success
10.3 Remove Custos WWD from LoRa Network
- If you need to remove the Custos from a LoRaWAN Network and possibly move it to another
LoRaWAN Network.
i.Remove Device information form LoRa Server, "Please refer to related LoRa Server user manual".
ii.Perform Factory Default Reset as item 10.4.
iii.Follow below procedure to start Exclusion procedure in Custos WWD.

Figure 10A Figure 10B
13
- To remove all Custos WWD settings without involve LoRa Gateway or LoRa Server.
i.Pick up the Custos WWD;
ii.Shaking it as picture below (10A), you will get “beep” sound and Green LED blinking,
iii.Lay WWD at and wait for 2 sec, then You'll get 2 Buzzer Sounds with Green LED Lights 2
times.
iv.Roll the WWD as shown in (10B) so that all 4 sides of the WWD are facing down once.
