1. Introduction

R718A01, mainly used to detect the temperature and humidity at low temperature environment such as the freezer air. 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 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. (users may need a screwdriver to open)

Turn on

Press and hold the function key for 3 seconds till the green 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. At 1st -5th second after power on, the device will be in 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

Fail to join the network

Suggest to check the device registration 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 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

Low Voltage

3.2V

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 = 15 min = 900s

MinTime : Min Interval = 15 min = 900s (the current voltage value is detected every Min Interval)

BatteryChange: 0x01 (0.1V)

TemperatureChange:0x0064 (1℃)

HumidityChange:0x0064 (1%)

Data Storage Function

1. R718A01 has the function of temperature and humidity data storage, and the upper limit of stored data is 50 packets

(if more than 50 packets, the initially stored data will be overwritten. For example, the data in packet 51 covers packet 1,

and the data in packet 52 covers packet 2, and so on)

2. Users read the data they want to find by issuing command ”ReadBackUpDataReq”

3. When issuing the ReadBackUpDataReq command, the UplinkCounter is based on the serial number (Fcnt) on the network

server. For example, if fcnt = 51 on the network server, downlink port 12, 0100000033 *(33Hex = 51Dec)

4. If the fcnt belongs to a non-temperature and humidity packet or there is no fcnt, reply no found.

5. Only the temperature and humidity data are stored, others such as battery power and time data are not stored.

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.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver

http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

5.1 Data Storage Function

FPort: 0x0C

Ex1.

Downlink: 0100000001 // Read Fcnt 1 data

Respond: 8100000001000A721745 // Temperature = 26.74°, Humidity = 59.57%

0A72 Hex = 2674Dec

1745 Hex = 5957Dec

Ex2.

Downlink: 0100000033 // Read Fcnt 51 data

Respond: 8100000033000A281770 // Temperature = 26°, Humidity = 60%

At this time, if fcnt 1 is read again, the data will not be found because it has been overwritten by fcnt 51.

Note:

1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect

data.

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.
