1. Introduction
R718AB, mainly used to detect the temperature and humidity. It collects data over LoRa network and
sends it to devices to be shown, fully compatible with LoRa protocol.
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.

The device will immediately send a version packet report along with an uplink packet including temperature,
humidity 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)
TemperatureChange:0x0064 (1℃)
HumidityChange:0x064 (0.1%)
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

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

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 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.
1. The Wireless Temperature and Humidity
Sensor sensor(R718AB) has a built-in magnet
(see Figure 1 below). When installed, it can be
attached to the surface of an object with iron
which is convenient and quick.
To make the installation more secure, use screws
(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.
The figure shows the scene where the temperature and
humidity sensor (R718AB) is applied in the refrigerator.
It can also be applied to the following scenarios:
⚫Restaurant (refrigerator or freezer)
⚫Shopping mall supermarket (freezer)
⚫Engine room
⚫Environmental monitoring
⚫Smart city and intelligent building
⚫Storage and transportation of food and medicine
⚫Flowers and other perishable foods
⚫Wall or logistics refrigerator
When it is necessary to detect temperature or humidity.
4. When the temperature and humidity detected by
R718AB is compared with the last reported values,
when the temperature change is exceeded 1°C (default)
or the humidity change is exceeded 1%(default),it will
report current values.

11
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.
Note on battery use:
Because the passivation of the ER battery electrode surface is an inherent characteristic of lithium thionyl
chloride batteries, before using the ER14505 3.6V 2400mAh lithium thionyl chloride battery, the user can
use a 33 ohm resistor to activate the battery for 1 minute to actively eliminate the battery hysteresis.

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.
