1. Introduction
R718AD, mainly used to detect the temperature. 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 famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It
can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic
meter reading, building automation equipment, wireless security systems, 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.

The device will immediately send a version package report and a report data with temperature and voltage values after the
device is powered on.
The device sends data in the default configuration before any configuration is done.
Default setting
Max Interval =15 min
Min Interval =15 min ( by default, the current voltage value is detected every Min Interval )
Battery Change = 0x01 (0.1V)
Temperature Change = 0x0064 (1 ℃)
Note:
1. The data transmission cycle of the device is subject to the real programming configuration before shipment.
2. The interval between two reports must be the minimum time(if there is special custom shipment, the setting will be
changed according to customer requirements)
The data reported by the device can be decoded with the Netvox LoraWANApplication Command document and
http://loraresolver.netvoxcloud.com:8888/page/index

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.
Note: To install the battery, use a screwdriver or similar tool to assist in opening the battery cover.
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.
