Introduction
The R718PG 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 inter operability between devices and gateways from different
manufacturers.

| Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a data report according to Min Interval.
Data Report
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 = 1 5 min 900s
- MinTime: M in Interval = 1 5 min 900s
- BatteryChange: 0x01 (0 Illuminance)
- Change: 0x00 32 50 Lux Illuminance detection
- range: 0 157000 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 Netv ox Lora Command Res olver http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.
Data report configuration and send ing period are as following:
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 between 1~65535| Can not be 0.| Report

Example of Report configuration:
| Bytes | 1 | 1 | Var(Fix =9 Bytes) |
|---|---|---|---|

Example for MinTime/MaxTime logic:
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e.
BatteryVoltageChange=0.1V
Note : MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration regardless B aatteryVoltageChange value.
Example#2
based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e.
BatteryVoltageChange= 0.1V.
Example#3
based on Min Time = 15 Minutes, MaxTime= 1 Hour, Repo rtabl e Change i.e.
BatteryVoltageChange= 0.1V.
MaxTime
Wakes up and collects data 3.5 V | 3.5 3.6 |=0.1 REPORTS 3.5 V. Users push the
button, REPORTS 3.5 V. Recalculate MaxTime.
Note
- 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 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.
- 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.
- 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.
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.
-
Light Sensor R718PG has a built in magnet (see Figure 1 below),When installed, the back of it can be adsorbed onthe 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 surfa ce (see Figure 2 bel ow).
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.
-
Compare the illumi nation value detect ed by the illumination sensor wi th the set illumination value . The detected value exceeds the set value (default 50 L ux ), the currently detected illumination value is sent. Light Sensor R718PG is suitable for the fo llowin g scenarios:
- Family
- School
- Storage room
- Hospital
- Bar
- Stairs
- Agricultural greenhouse
To detect the illumination value.
Note: Please do not disassemble the device unless it is required to replace the batteries. Do not touch the waterpro of gasket, LED indicator light, function k eys when replacing the batteries. Please use suitable screwdriver to tighten the screws (if using an elect ric screwdriver, it is recommended to set the torque as 4kgf) to ensure the device is impermeable.
Information about Battery Passivation
Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density. However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation. As a result, please make sure to source batteries from reliable vendors, and the batteries should be produced within the last three months. If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
- To determine whether a battery requires activation Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit. If the voltage is below 3.3V, it means the battery requires activation.
- How to activate the battery
- Connect a battery to a 68ohm resistor in parallel
- Keep the connection for 6~8 minutes
- The voltage of the circuit should be ≧3.3V
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.
