1. Introduction
R313LA is a Wireless Infrared Proximity Sensor for Netvox ClassAtype devices based on the LoRaWAN open protocol.
It has an infrared proximity sensor that can detect if there is object (toilet paper) existing within its detection range and transmits the
detected data to gateway for display via a wireless network.
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 flat screwdriver or other tools to open the battery cover)
Insert two sections 3V CR2450 button batteries and close the battery cover.
Note: Require 2 button batteries to supply power at the same time.
Turn on Press any function key until the red and green indicator lights flash at the same time: success
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, and the device memorizes previous on/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. If press any function key and insert batteries at the same time, it will enter engineer testing
mode.

The green indicator remains off: fail
Fail to join the network Suggest to check the device verification information on the gateway or consult your platform
server provider.
Function Key
Press and hold for 5 seconds
Restore to factory setting / Turn off
The green indicator flashes 20 times: success
The green indicator remains off: fail
Press once The device is in the network: the green indicator flashes once and sends a report
The device is not in the network: the green indicator remains off
Sleeping Mode
The device is on and in the network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes, a data report is sent
according to Min Interval.

5. Data Report
After the device is powered, it will immediately send a version package and an attribute report data that reports the current status
of the object and the raw data of infrared range.
The device sends data according to the default configuration before any other configuring.
Default Setting
Maximum time: 3600s
Minimum time: 3600s (By default, the current is detected every MinTime.)
Battery: 0x01 (0.1V)
OnDistanceThreshold :0xC409 little-endian (2500)
* Distance Threshold value is used little-endian;
When you need configure distance threshold default setting, please change to little-endian,
for example 2500(Hex) =9C4(Dec) is big-endian and 0xC409 is little-endian
Determining the status of the object
(1)The raw data of detection of infrared ranging is greater than the OnDistanceThreshold parameter
setting value, the status would be 1, indicating the presence of the object.
(2)The raw data of detection of infrared ranging is smaller than the OnDistanceThreshold parameter
setting value, the status would be 0, indicating the absence of the object
Threshold setting instructions
A. First of all, fix the location of the device.
B. When first detection appears no object, the device detects RawSenseData (infrared ranging
data), assuming A (2400)
C. Then detect again appears there is object, the device detects RawSenseData (infrared ranging
data), assuming B (4000)
D. The range of Threshold(X) is set: A（2400）< X < B（4000）, it would recommend to take a
value in the middle of range.
E. The RawSenseData value has no unit and is a signal value of a distance.
The closer the device is to the detected object, the larger the value; the farther the device is to the detected object, the
smaller the value.

6
Note:
1. The cycle of the device sending the data report is according to the default.
2. The interval between two reports must be the MinTime.
3. If there are special customized shipments, the settings will be changed according to customer’s
requirement.

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 change value 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. Remove the 3M release paper on the back of
the device and attach the device to the smooth wall (please
do not stick it to the rough wall to avoid falling off after a
longtime usage).
Note
Wipe the wall surface before installation to avoid dust on
the wall surface that affect the effect of the paste.
Do not install the device in a metal shielded box or other
electrical equipment around it to avoid affecting the
wireless transmission of the device.
2. According to the situation of different paper boxes, choose
the appropriate installation position.
Take the large roll paper box as an example, as the right
figure.
3. The status bits for judging whether there is toilet paper are
as follows:
A. The raw data of infrared distance measurement
(RawSenseData) is greater than the setting value of
parameter -- OnDistanceThreshold.
The status bit is 1 indicating that there is toilet paper.
B. The raw data of infrared distance measurement
(RawSenseData) detection is less than or equal to the
setting value of parameter -- OnDistanceThreshold.
The status bit is 0 indicating that there is no toilet paper.
Note:
RawSenseData is the approach signal value.
The closer the device is to the detected object, the larger the
value; otherwise, the smaller the value.
R313LA can be used in the toilet to detect whether the toilet
paper is used up.

Battery Installation Steps:
Warning: When replacing the battery, it must be done by professionals.
Please must use 2 CR2450 batteries for this device, and a single battery specification is 3V.
Please note that the positive and negative poles of the battery are not reversed.
Step 1: Use a flat screwdriver, along the opening of the back cover (the red frame in the Fig. 1.),
gently press it toward the center of the device, and then remove the battery back cover toward the back of the
device (with sticker).
Fig. 1.
Step 2: Put 2 batteries into the battery slot, please note that the positive pole of the battery is facing up and the negative pole is facing
down.
Fig. 2. Fig. 3.
Step 3: First align the side groove of the battery back cover with the protruding points of the host body (the red frame in Fig. 2.), and
then close the battery back cover.

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case
the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt
some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which
will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly. Please take it to the nearest authorized service facility for repairing.
