1. Introduction

R718DB is identified as a LoRaWAN ClassA device with a spring-loaded vibration sensor and compatible with LoRaWAN

protocol.

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.

4.Set up Instruction

On/Off

Power on Insert batteries (Users may need a screwdriver to open)

Turn on Press and hold the function key for 3 seconds and the green indicator flash once.

Turn off (Restore to factory setting) Press and hold the function key for 5 seconds and the green indicator flashes 20 times.

Power off Remove Batteries.

Note:

1. Remove and insert the battery; the device is at off state by default.

2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor

inductance and other energy storage components.

3. For the first 5 second after powering on, the device will be in engineering test mode.

Network Joining

Never joined the network

Turn on the device to search the network to join.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

Turn on the device to search the previous network to join.

The green indicator stays on for 5 seconds: success

Report

per Max Interval

The device will immediately send a version packet report and the vibration report data

The device sends data in the default configuration before any configuration is done.

Default setting:

MaxTime: Max Interval = 60 min = 3600s

MinTime: Min Interval = 60 min = 3600s

BatteryVoltageChange: 0x01 (0.1V)

R718DB trigger:

When any way of the sensor senses the vibration and the spring deforms, an alarm message willbe reported.

The vibration is “1”.

No vibration is “0”.

The vibration Restore Configuration:

The Restore function is used to send the final static status of the device.

(Please refer to the configuration command format below.)

Restore = 0, no data will be sent when the device is rest.

The data is sent with the next report.

Restore = 1, the data will be sent with a vibration bit-- 0 after the device is rest for 5 seconds.

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

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

value.

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

MaxTime

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

1. The device has a built-in magnet.

When installed, it can be attached to the surface of an

object with iron which is convenient and quick.

To make the installation more secure, use screws

(purchased) to secure the unit to a wall or other surface

Note:

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

environment with other electrical equipment around it to

avoid affecting the wireless transmission of the device.

2. Fix the vibration sensor of the vibration sensor on the

object that needs to be detected whether it is vibrating

(here, take the mousetrap as a picture.)

Videolink:Mouse trap

3.The figure shows the vibration sensor (R718DB)

applied to the scene of the mousetrap in the restaurant.

It can also be applied to the following scenarios:

●Restaurant (rat)

●Shopping mall supermarket (rat)

●Engine room (rat)

When it is necessary to detect whether the object is

vibrating or moved.

4. When the vibration sensor detects a vibration, it

immediately sends an "alarm" message.

When the device reports data periodically, it restores

the "normal" status and sends "normal" status

information. Moreover, enable the Restore function

and the “normal” status will be sent after the device

stops for 5 seconds.

Note:

The shaking alarm bit is “1”.

The static and non-shaking alarm bit is “0”.
