1. Introduction

R718WAA is an alarm device for water leakage detection of netvox ClassA type device based on LoRaWAN open protocol,

which is compatible with LoRaWAN protocol. When the sensor of R718WAA detects water leakage, R718WAA will send

alarm information and temperature and humidity to the gateway. When the sensor detects that there is no water leakage, it will

send the information that the state returns to normal and the temperature and humidity to the gateway.

LoRa Wireless Technology:

LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other

communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance.

Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation

equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption,

transmission distance, anti-interference ability and so on.

LoRaWAN:

LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and

gateways from different manufacturers.

per Max Interval

The device will immediately send a version packet report along with an uplink packet including water leak status, temperature,

humidity and battery voltage. The device sends data in the default configuration before any configuration is done.

Default setting:

MaxTime: 3600s (if there is special customized shipment, the setting will change according to the customer's requirements)

MinTime: 3600s (by default, the current voltage value is detected every min interval)

Battery Change: 0x01 (Unit:0.1v, 0.1V)

Temperature Change: 0x64 (Unit:0.01°, 1°C)

Humidity Change: 0x64 (Unit:0.01%, 1%)

Water leak detection:

When R718WAA detects water leakage, it will immediately report a leak status as "1"

When R718WAA does not detect water leakage, it will immediately report a leak status as "0"

Note:

The device report interval will be programmed based on the default firmware which may vary.

The interval between two reports must be the minimum time.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver to resolve uplink data.

MaxTime MaxTime

Sleeping(MinTime) Sleeping(MinTime)

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange

value.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

MaxTime

Sleeping(MinTime) sleeping sleeping sleeping

0H 15th M 30th M 45th M 1H 2H

Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

MaxTime

sleeping sleeping ...

0H 15th M 30th M 45th M 1H 1H 10th M 1H 25th M 1H 40th M 1H 55th M 2H 10th M

Notes :

1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not

collect data.

2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value,

the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device

reports according to MaxTime interval.

3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up

frequently and the battery will be drained soon.

4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another

cycle of MinTime/MaxTime calculation is started.

6. Installation

When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall with screws.

1.The Wireless Water Leak Detector/Temperature/Humidity Sensor

(R718WAA) has a built-in magnet (as Figure 1 below).

It can be attached to the surface with iron material during

installation.

To make the installation more secure, please use screws

(purchased separately) to fix the device on the wall or other

objects

Note:

Do not install the device in a metal shielded box or in an

environment surrounded by other electrical equipment to avoid

affecting the wireless transmission of the device.

3. When the sensor probe detects the leak, the device

will send an "alarm" message.

After remove the probe from the accumulated leakage

and drain the remaining water from the sensor, the

device will restore to the "normal" state and send the

"normal" status message.

2. Remove the 3M release paper (as the red part of the

above figure) on the back of the sensor probe and

attach it to the smooth ground that may accumulate

leakage (as the right figure).

The R718WAA can be used in the following scenarios:

Data centers and rooms.

File storage center.

Basement leakage detection

Water pipe leakage detection

The bottom of the cabin detection

This device is designed to detect water leakage and is not suitable

for detecting hazardous chemical, solvent, oil, fuel, strong acid or

other corrosive liquid.

Note: Please do not disassemble the device unless it is required to replace the batteries. Do not touch the waterproof gasket, LED

indicator light, function keys when replacing the batteries. Please use suitable screwdriver to tighten the screws (if using an electric

screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable.
