1. Introduction
R718PE02D is a wireless communication device for Netvox Class C device based on LoRaWAN open protocol. It is a wireless
communication device for the material level detection industry that uses LiDAR radar for single-point ranging. Based on the ToF (Time
of Flight) schematic, the R718PE02D provides stable, accurate, and reliable ranging performance by optimizing the optical system and
built-in algorithms. It is not easily affected by the surface state of the detected object, and the ranging performance can reach up to 25m.
The product is equipped with a unique dust-removal wiper structure. The radar-driven dust-removal wiper can complete the dust removal
operation of the optical mirror, so it can maintain the accuracy of distance measurement in an environment with severe dust pollution and
dust accumulation. The R718PE02D body and the LiDAR sensor communicate through the UART serial communication and transmit
the detected data to other devices for display through the wireless network. It adopts a wireless communication method that conforms to
the LoRaTM protocol standard.
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, and industrial monitoring. The 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.

5 Data Report
After power on, the device will immediately send a version packet report and an attribute packet report.
The device sends data according to the default configuration before any other configuration.
Default:
Max Interval = 0x0384 (900s)
Min Interval = 0x0384 (900s) (detect the material level and voltage at every Min Interval)
reportchange: batteryvoltagechange ---- 0x01 (0.1V)
distancechange ---- 0x012C (300mm)
The interval of the data reports might vary due to the firmware.
R718PE02D default Max Interval = 15min and Min Interval = 15min. (The intervals could be set based on customers’ demands.)
R718PE02D reports the distance between sensor and material, the percentage of the material level, and the ranging range.
Note: 1. The dust removal wiper will automatically wipe once when the device report cycle is reached or when the button is
pressed.
2. The blind zone distance of the sensor is ≤ 0.1m.

6. Application
In the case of detecting the material level of the barn, the device is installed on the top of the barn, and the device is powered on after
fixing. The device collects the distance between the material level and the sensor and the percentage of the material level in the barn at
regular intervals.
H: The height of the barn (this value can be set with the payload command; the “fillmaxdistance” in payload means H)
D: The distance between the device and the material (this value is “distance” in uplinks)
L: The material level (this value can be calculated by the “distance” in uplink and “fillmaxdistance” in payload)
Calculation: L = fillmaxdistacnce –distance
d: The DeadZoneDeistance set by the device (the distance that cannot be detected by the actual device)
FillLevel: The percentage of the material level in the barn. (Status = 0)
The value of the total height of the barn can be set through commands according to the specific scene.
Illustration 1 Illustration 2
FillLevel = ((H - D) / H) * 100% FillLevel = ((H - D) / H-d) * 100%
Note:
The ranging range of the device is:
90% reflectivity, 0Klux 0.1m~25m; 10% reflectivity, 0Klux 0.1m~12m;
90% reflectivity, 100Klux 0.1m~25m; 10% reflectivity, 100Klux 0.1m~12m
The calculate method of material level percentage of
DeadZoneDistance can be set.

7. Installation
7.1 Precautions for sensor:
1. When installing the sensor, it is recommended to use M2.5 round head Phillips screws for installation.
Please remove the protective film of the optical lens before use. The lens of front panel of LiDAR cannot be covered. Please keep
it clean. The surface of optical lens is the ranging zero of LiDAR.
2. The detection angle of the sensor is 3°. At different distances, the size of light spot, namely the edge length of the detection range,
is different.
The spot size at different distances
3. Side length of the detection range at different distances (the detection range is a square)

Note: The side length of the detected target object should be greater than the side length of the detection range of the sensor. When
the side length of the detected object is smaller than the side length of the detection range, the effective range of the radar
will be reduced. When detecting a slope, the sensor can be placed in the middle of the slope.
4. Maintenance and Cleaning
⚫Before/after turning on the device, please check the exposed window mirror and check whether the optical components are dirty,
if dirty, please clean it in time.
⚫The optical components should be cleaned regularly because the device will be placed and operated in a harsh environment.

14
⚫Before cleaning, please turn off the device first, and use a soft cloth to gently wipe the window in the same direction, avoiding
