1. Introduction
R711Ais a long distance wireless temperature sensor based on LoRaWANTM protocol (Class A). It is compatible with LoRaWAN
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.

5. Data Report
The device will immediately send a version package report and a data report including the voltage and temperature.
The device sends data according to the default configuration before any other configuring.
Default setting:
MaxTime: Max Interval = 60min = 3600s
MinTime: Min Interval = 60min = 3600s
Temperature Change = 0x0064 (1 ℃)
Battery Change = 0x01 (0.1V)
Note:
1. The cycle of the device sending the data report is according to the default.
2. The interval between two reports must be MinTime.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver
http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

Note:

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 change value 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.

7. Installation
This product does not have a waterproof function. After the join into LoRa network,
please place it indoors.
Temperature and Humidity Sensor (R711A) is suitable for the
following scenarios:
⚫Family
⚫School
⚫Kindergarten
⚫Office
⚫Archive room
⚫Machine room
⚫Museum
⚫Art Museum
Where need to detect the temperature
1. Please screw the bracket into the wall.
2. Put R711A into the bracket
3.When the temperature detected by the temperature sensor is
compared with the last reported temperature value and
exceeds the set value (the temperature defaults to 1°C), that
is, the temperature exceeds 1 °C, the currently detected
value is sent.
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.

8. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case
the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt
some plastic parts.
• Do not store in excessive cold place. 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. Treating equipment roughly can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding.
Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repairing.
