1. Introduction
R313G is a long-distance light sensor based on the LoRaWAN open protocol (Class A).
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.

4. Set up Instruction
On/Off
Power on
Insert batteries (users may need a screwdriver to open)
Insert two sections of 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 and indicator flashes once meaning it is turned on successfully.
Turn off (Restore to factory setting) Press and hold the function key for 5 seconds and green indicator flashes 20 times.
Power off Remove Batteries.
Note:
1. Remove and insert the battery; 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.

When the device is powered on and activated, it will immediately send a version package.
Data will be reported once per hour by default setting.
Default setting:
Maximum time: 3600s
Minimum time: 3600s
BatteryChange: 0x01 (0.1V)
IlluminanceChange:0x32 (50 lux)
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. R313G defaults Max Interval = 3600s, Min Interval = 3600s
(If there are special customized shipments, the settings will be changed according to customer’s requirement.)
The reported data is decoded by the Netvox LoRaWAN Application Command document and

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) This product does not have a waterproof function. After the joining is completed, please place it indoors.
(2) The dust in the installation position of the equipment needs to be wiped clean and then affixed to the equipment.
(3) The battery installation method is shown in the figure below (battery with "+" facing outward).
Note:
To install the battery, use a screwdriver or similar tool to assist in opening the battery cover.
1. Remove the 3M adhesive on the back of the light sensor and
attach the device to the position where the light value needs to
be detected (please do not stick it to a rough surface to
prevent the device from falling off after a long time).
Note:
(1)Wipe the surface clean before installation to avoid dust on
the surface and affect the adhesion of the device.
(2)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. When the illumination value detected by the illumination
sensor is compared with the last reported illumination value,
when the set value is exceeded (default 50 lux), the currently
detected illumination value is sent.
This
figure shows the scene where the light sensor (R311G)
is applied in the office.
It can also be applied to the following scenarios:
Home
School
Storage room
Hospital
Bar
Stairs
Agricultural greenhouse
Places which need to detect the illumination value

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets
wet, please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy
batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate
structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest
authorized service facility for repair.
