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.

4.Set up Instruction

On/Off

Power on

Insert 2 section AA 1.5V batteries

Turn on

Press the function key till the green and red indicator flashes once.

Turn off

(Restore to factory setting)

Press and hold the function key for 5 seconds till green indicator flashes for 20

times.

Power off

Remove Batteries.

Note

1. Remove and insert the battery; the device is at off state by default.

2. On/off interval is suggested to be about 10 seconds to avoid the interference

of capacitor inductance and other energy storage components.

3. Hold the function key and insert batteries, the device will be into engineering

test mode.

Network Joining

Never joined the network

Turn on the device to search the network to join.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

(not at factory setting)

Turn on the device to search the previous network to join.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Function Key

Press and hold for 5

seconds

Restore to factory setting / Turn off

The green indicator flashes for 20 times: success

The green indicator remains off: fail

Press once

The device is in the network: green indicator flashes once and sends a report

The device is not in the network: 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.

Low Voltage Warning

5. Data Report

Data report configuration and sending period are as following:

Min Interval

Report

per Min Interval

Report

per Max Interval

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.

Example for MinTime/MaxTime logic:

Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e.

BatteryVoltageChange=0.1V

MaxTime MaxTime

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.
