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.

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.

7. 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 it is suggested that if the storage period is more
than one month from the date of battery production, all the batteries should be activated.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.
ER14505 Battery Passivation:
7.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.
7.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes
c. The voltage of the circuit should be ≧3.3, indicating successful activation.

8. 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.
