1. Introduction
R712 is a long-range wireless outdoor temperature and humidity device based on the LoRaWAN
open protocol (Class A).
The R712 is mainly used to detect the temperature and humidity in outdoor air, and also carrying a
waterproof housing. It collects data over LoRa network and sends it to devices to be shown, fully
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.

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 = 60 min=3600s
MinTime:Min Interval = 60 min =3600s
BatteryChange: 0x01 (0.1V)
TemperatureChange:0x0064 (1℃)
HumidityChange:0x0064 (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.

Note: MaxTime=MinTime. Data will only be report according to MaxTime (MinTime) duration
regardless BatteryVoltageChange value.

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.

R712_User_Manual_CHS_20200713
1.Take out the temperature and humidity sensor
and the base of it from the housing (as shown
below).
Steps:
Press the buttons on both sides of the base (as
shown in the below picture), then gently take out
the sensor inside the housing.
Note:
Please keep the device from metal or other
electrical equipment to avoid affecting the
wireless transmission of the device.
2. Insert the battery into the sensor, then replace
the sensor and base into the housing.
Note that the protruding part of the base should be
aligned with the concave part of the housing (red
frame below).
3. Unscrew the nut of the red circle below and
lock the device to the tube as shown below.
The outdoor temperature and humidity sensor
(R712) is suitable for the following scenarios:
⚫Smart agriculture
⚫Environmental monitoring
When it is necessary to detect temperature or
humidity outdoors
4. When the temperature and humidity detected
by R712 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.
5.Installation height recommendation:1-1.5 m
6.Installation ambient temperature: -20C°~55°C

11
Battery installation steps
The device must use 2 sections of AA 1.5V Alkaline batteries
Step 1

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.
