1. Introduction

The R718G is a Wireless Light Sensor for Netvox ClassA type devices based on the LoRaWAN open protocol and is compatible

with the LoRaWAN protocol. It can detect illuminance anywhere, ex. sunlight, outdoor area.

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.

Report

per Min Interval

Report

per Max Interval

The device will immediately send a version packet report along with an uplink packet including illuminance and battery

voltage.

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

Default setting:

MaxTime : Max Interval = 15 min = 900s

MinTime : Min Interval = 15 min = 900s

BatteryChange: 0x01 (0.1V)

IlluminanceChange:0x0032 (50 Lux)

Illuminance detection range:

0x00 3~65000 Lux (default)

0x01 3~130000 Lux

0x02 3-220000 Lux

Note:

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

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.

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless BatteryVoltageChange

value.

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

MaxTime

0H 15th M 30th M 45th M 1H 1H 10th M 1H 25th M 1H 40th M 1H 55th M 2H 10th M

Note:

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 variation 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

This product comes with waterproof function. When using it, the back of it can be adsorbed on the iron surface, or the two ends

can be fixed to the wall with screws.

Note:

Please do not disassemble the device unless it is required to replace the batteries.

Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries. Please use suitable

screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as 4kgf) to ensure the

device is impermeable.

Light Sensor (R718G) is suitable for the following

scenarios:

⚫Family

⚫School

⚫Storage room

⚫Hospital

⚫Bar

⚫Stairs

⚫Agricultural greenhouse

To detect the illumination value.

1. Light Sensor（R718G）has a built-in magnet (see

Figure 1 below),When installed, the back of it can be

adsorbed on the iron surface, or the two ends can be

fixed to the wall with screws (should be purchased) to

secure the unit to a wall or other surface (see Figure 2

below).

Note

Do not install the device in a metal shielded box or in

an environment with other electrical equipment around

it to avoid affecting the wireless transmission of the

device.

2. Compare the illumination value detected by the

illumination sensor with the set illumination value. The

detected value exceeds the set value (default 50 Lux), the

currently detected illumination value is sent.
