1. Introduction

The R718X is a LoRaWAN Class A device and it is compatible with LoRaWAN protocol. R718X has a built-in ultrasonic ranging

sensor that can detect the distance from the sensor to the detected object (for example: detect the height of garbage in the waste

bin). R718X also has tilt angle and temperature detection function, it can detect the tilt angle and temperature of the waste bin.

R718X would send out the detected data through wireless network.

LoRa Wireless Technology:

LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared

with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It

can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic

meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,

low power consumption, long transmission distance, strong 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.

Any number between

1~65535 Can not be 0. Report

per Min Interval

Report

per Max Interval

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

angle of tilt, fill level of percentage.

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

Default Setting:

MaxTime: Max Interval = 15 min = 900s

MinTime: Max Interval = 15 min = 900s

BatteryChange = 0x01 (0.1v)

DistanceChange = 0x012C (300mm)

TemperatureChange = 0x0A (1°C)

OnDistanceThreshold = 0x01F4 (500mm)

FillMaxDistance = 0x07D0 (2000mm)

AngleChange = 0x0F (15°) *Cannot be modified

Data packet:

a. When used in waste bin detection:Distance, Temperature, AngleofInclination, FillLevel;

Status=0 (Invalid)

b. When used in parking detection: Status, Distance, Temperature, AngleofInclination;

FillLevel=0 (Invalid)

Note:

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

(2) The interval between two reports must be the minimum time.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver

http://www.netvox.com.cn:8888/page/index to resolve uplink data.

*The mode switches via setting the value of FillMaxDistance and OnDistanceThreshold.

If the current mode of the device is waste bin detection, it can be switched to the parking detection by setting FillMaxDistance to

0 first, and then setting OnDistanceThreshold.

Conversely, the current mode of the device is parking detection, it can be switched to the waste bin detection by setting

OnDistanceThreshold to 0 first, and then setting FillMaxDistance.
