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 extends the communication distance. It can be widely used in any use case that requires long-distance and low-data wireless communications. Examples, automatic meter reading, building automation equipment, wireless security systems, and 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.

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 the 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:| Remove and insert the battery; the device memorizes the previous on/off state by default.
The on/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.
If press any function key and insert batteries at the same time, it will enter engineer testing mode.
Network Joining
Never joined the network| Turn on the device to search the network.
The green indicator stays on for 5 seconds: success The green indicator remains off: fail
Had joined the network(not restored to the factory setting)| Turn on the device to search the previous network.
The green indicator stays on for 5 seconds: success The green indicator remains off: fail
Fail to join the network| Suggest checking the device verification information on the gateway or consulting your platform service 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: 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 report change exceeds the setting value or the state changes: send a data report according to Min Interval.

Low Voltage Warning

Low Voltage	2.4V

Data Report

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:

The cycle of the device sending the data report is according to the default.
The interval between two reports must be the MinTime.
R313G defaults Max Interval = 3600s, Min Interval = 3600s (If there are specially customized shipments, the settings will be changed according to the customer’s requirement.)

The reported data is decoded by the Netvox LoRaWAN Application Command document and http://www.netvox.com.cn:8888/page/index
Data report configuration and sending period are as follows:

Min Interval (Unit: second)| Max Interval (Unit: second)| Reportable Change| Current Change≥ Reportable Change| Current Change＜Reportable Change
---|---|---|---|---
Any number between 1~65535| Any number between1~65535| Can not be 0.| Reportper Min Interval| Report per Max Interval

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

MaxTime=MinTime. Data will only be reported according to Maxime (MinTime) duration regardless BatteryVoltageChange
Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

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

Notes:

The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
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 the MinTime interval. If the data variation is not greater than the last data reported, the device reports according to the Maxime interval.
We do not recommend setting 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.
Whenever the device sends a report, no matter the resulting of data variation, button push or Maxime interval, another cycle of MinTime / Maxime calculation is started.

Installation

This product does not have a waterproof function. After the joining is completed, please place it indoors.
The dust in the installation position of the equipment needs to be wiped clean and then affixed to the equipment.

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:

Wipe the surface clean before installation to avoid dust on the surface and affecting the adhesion of the device.
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.

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 that need to detect the illumination value
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.
(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.

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 a dusty or dirty environment. It might damage its detachable parts and electronic components.
Do not store the device under excessive heat conditions. 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 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.
