1. Introduction
R711 is a long distance wireless temperature and humidity sensor based on LoRaWAN open protocol (Class A).
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.

4. Set up Instruction
On/Off
Power on
Insert batteries. (Open the battery back cover and insert two 1.5V AA size
batteries into the battery slot)
Turn on Press and hold the function key till the green indicator flashes once.
Turn off
(Restore to factory setting)
Press and hold the function key for 5 seconds till the green indicator flashes
20 times.
Power off Remove batteries
Note
1. After insert batteries and press the button at the same time, the device
will be in engineering test mode.
2. Remove and insert the battery; the device will remember the previous
on/off status by default.
3. On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage
components.

Suggest to check the device verification information on the gateway or
consult your platform server provider.
Function Key
Press and hold for 5 seconds
Restore to factory setting / Turn off

The green indicator remains off: fail
Press once
The device is in the network: The green indicator flashes once and sends a
data report
The device is not in the network: The green indicator remains off
Sleeping Mode
The device is on and in the
network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a
data report according to Min Interval.
The device is on but not in
the network
1. Suggest to remove batteries if the device is not used.
2. Suggest to check device verification on gateway.
Low Voltage Warning
Low Voltage 2.4V

5. Data Report
The device will immediately send a version package report and a data report including the voltage,
temperature, and humidity,
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
*By default, the current voltage is detected every Min Interval.
Default reportchange: Ambient temperature -- 0x0064 (1 ℃)
Ambient humidity -- 0x0064 (1%)
Battery -- 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://www.netvox.com.cn:8888/page/index to resolve uplink data.

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
BtteryVoltageChange value.
Example#2 based on
MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
Example#3 based on
MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.
Notes:

8
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 (R711) is
suitable for the following scenarios:
Family
School
Kindergarten
Office
Archive room
Machine room
Museum
Art Museum
When it is necessary to detect temperature or
humidity place
1. Please screw the bracket into the wall.
2. Put R711 into the bracket
3.When the temperature (or humidity) detected by the
temperature and humidity sensor is compared with
the last reported temperature value (or humidity
value), when the set value is exceeded (the
temperature defaults to 1°C; the humidity defaults to
1%), that is, the temperature exceeds 1 °C ( or
humidity exceeds 1%), 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.
