UBITECH Custos Wireless Water Detector

INTRODUCTION

What’s LoRa

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.

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 configuration).

ACTION SENSOR & INDICATORS BEHAVIOR

3-axis Action Sensor

• Built-in 3-Axis Accelerometer for gesture recognition by detecting a series of movements, Once the 3-Axis Action Sensor is activated, you also can see below Visual and Sound Indicators response with the 3-Axis Action Sensor.

Visual Indicator

• 3 Colors LED: GREEN, YELLOW & RED
• ON Event: ON, quick blinking and slow blinking

Sound Indicator

• Buzzer: Long & short beep sound.

HOW CUSTOS WWD WORKS

3-axis Actions Sensor – Gesture Recognition Procedure

• 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 defined function, such as below functions
  1. To wake up Custos WWD from sleep mode and send out uplink packet to Gateway / LoRa Server,
  2. Factory Default Reset,
• Custos WWD only supports below gesture movement, shake it vertically or horizontally as below.

HOW WATER LEAK SENSOR WORKS

Water Detection Probes

• Custos WWD supports two Water Detection Probes “Built-in & Remove”,

Built-in Water Detection Probe

• WWD has special recess which helps induce Water run through it, to create effective detection by probes from both end
• To achieve better result, please put the WWD on the floor flatly

Remote Water Detection Probe

• To make sure Sensor Probe works properly show as below pictures, please make sure insert the Remove Sensor Probe tightly and there is no any gap allowed between 3.5mm jack and housing.

WORKING MODE SUPPORT

Shipping Mode (Deep Sleep Mode)

• By default, Custos WWD is set in Shipping Mode to keep it in deep sleep to conserve battery for transportation & warehousing, in this time all functions will be disabled until unlocked it from Shipping Mode. End-customer must activate the device from Shipping Mode before joined to any LoRa Network

Standalone Mode

• If Custos WWD is not paired to any LoRa Network and it unlocked from Shipping Mode.

Network Mode

• Custos WWD is paired with a LoRa Network and it can join full benefits.
• Supported function as Water Leak Detection, Temperature Report and downlink configuration.
• Custos WWD also can associate with Custos BVS to shut off the Water Valve when detected Water Leak.

Water Leak Sensor & Alarm

• Water Leak Alarms refer to two Water Detection Probes “Built-in & Remote”

SETUP WITH LoRa NETWORK

Check Network Status

• By brand new default, Custos WWD does not belong to any LoRa Network and it is under shipping mode.
• To check Custos WWD Network status, trigger the Built-in Leak Sensor;
• Yellow LED flashing means Custos WWD is in Standalone mode, not joined in LoRa network.

OTAA Activations

• Custos LoRa WWD can support two methods to activate OTAA (time limit mode and forever mode)
  1. Periodically activate OTAA for 3 minutes only.
  2. Activate OTAA forever.

Time limit activate OTAA:

• OTAA will be activate only 3 minutes, after that if Custos WWD is not joined to any LoRa Network then it will return to shipping mode, this keeps lowers power consumption.
  1. Trigger Built-in Water Leak Sensor for 2 seconds comes with Yellow LED Lights on per seconds.
  2. OTAA will be started per 30 seconds automatically if it’s still remain in standalone mode.
  3. OTAA success with LoRa Server, 2 Buzzer Sounds and Green LEED on when OTAA success,
  4. After 3 minutes time-out without OTAA success then it will be back to shipping mode.

Activate OTAA and exits Shipping Mode permanently (Not recommended):

• OTAA will be activated forever until it joined into a LoRa Network and it will not return to shipping mode anymore,
  1. Trigger Built-in Water Leak Sensor for 5 seconds and comes with Yellow LED Lights on per seconds.
  2. OTAA will be started per 30 seconds automatically if it’s still remained in standalone mode.
  3. Yellow LED will keep flashing when OTAA is process with LoRa Server and 2 Buzzer Sounds and Green LEED on when OTAA success,

Remove Custos WWD from LoRa Network:

• If you need to remove the Custos from a LoRa Network and may move it to other LoRa Network,
  1. Remove Device information form LoRa Server, “Please refer to related LoRa Server user manual”;
  2. Perform Factory Default Reset as item 13.4;
  3. Follow below procedure to start Exclusion procedure in Custos WWD,

Factory Default Reset

• To remove all Custos WWD settings without involve LoRa Gateway or LoRa Server.
  1. Pick up the Custos WWD;
  2. Shaking it as illustration (10a) with 5 Buzzer sounds then stop and hold still for 2 seconds;
  3. You’ll get 2 Buzzer Sounds with Green LED Lights 2 times;
  4. Trigger the Built-in Leak Sensor as illustration (10b) for 10 seconds with Yellow LED Lights 5 times;
  5. Once success, Green LED Lights up while it’s reseting itself to factory state;
  6. Then WWD goes into hibernation (Shipping Mode).

BATTERY LEVEL

Battery Level Report

• The Battery Level Report will be sent through Uplink packet when triggered 3-Axis Action Sensor or Water Leak Sensor,
• Custos WWD sends Uplink packet with Battery Level Report,
• Following below procedure to start Battery Level Check,
• There’re three result of Battery Level UIs,
  1. Battery Full = 61 – 100%
  2. Battery Fair = 31 – 60%
  3. Battery Low < 30%

Low Battery Alarm

• Low Battery Alarm UI will be enabled when battery level less than 15% once triggered the 3D-Axis Action Sensor (Red LED flashing 2 time and buzzer sounds 2 times.)

WATER LEAK SENSOR & ALARM

Water Leak Detection & Alarm

• Once the Built-in or Remote Water Leak Sensor Probe is triggered, the Custos WWD sends Uplink packet with Water Leak Detected to LoRa Server automatically,
• End-user can configure to control Custos BVS to close the water Valve automatically in LoRa Server once it received Water Leak Detected signal from Custos WWD.
