1. Appearance

2. Introduction

The R718PB15 is a ClassA type device based on the LoRaWAN protocol.

The R718PB15 can be connected to the 5TE soil sensor, and the soil moisture /conductivity/temperature collected by the sensor is reported to the corresponding gateway.

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.

3. Main Characteristics

Compatible with LoRaWAN

2 sections of 3.6V power supply

Simple operation and setting

4. Operation

On/Off

Power on Insert batteries.

(users may need a flat blade 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 the green indicator flashes for 20 times.

Power off Remove batteries

Note:

1. At 1st-5th second after power on, the device will be in engineering test mode.

2. Remove and insert the battery; the device is at off state by default. Turn on the device to use again.

3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other

energy storage components.

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

(when the device is on)

First two mins: wake up every 15 seconds to send request.

After two mins: enter sleeping mode and wake up every 15 minutes to send request.

Note: Suggest to remove batteries if the device is not used to save power.

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 flashes for 20 times: success

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

First two mins: wake up every 15 seconds to send request.

After two mins: enter sleeping mode and wake up every 15 minutes to send request.

Note: Suggest to remove batteries if the device is not used.

Suggest to check device verification on gateway.

Low Voltage Warning

Low Voltage 3.2V

5. Data Report

The device will immediately send a version report report and soil moisture, soil conductivity and report data of soil temperature and voltage values;

The device sends data in the default configuration before any configuration is done.

Maximum time: Max Interval

Note: The device send data cycle has been programmed to be correct. There is no minimum time supported.

R718PB15 defaults Max Interval = 60min.

The R718PB15 device does not support the ReportChange function. That is, the configuration is invalid. The sent report data string is always sent

according to the ReportMaxTime cycle.

Note: The real data sending cycle will be programmed before shipment.

R718PB15 Report data type: soil moisture, soil conductivity and soil temperature.

Data report configuration and sending period are as following:

Configure device parameters MaxTime = 1min

Downlink 01570000003C0000000000

The device returns:

8157000000000000000000 (Configuration succeeded)

8157010000000000000000 (Configuration failed)

6. Installation

METHOD 1. HORIZONTAL INSTALLATION

1. Excavate a hole or trench a few centimeters deeper than the depth at which the sensor

is to be installed.

2. At the installation depth, shave off some soil from the vertical soil face exposing

undisturbed soil.

3. Insert the sensor into the undisturbed soil face until the entire sensor is inserted. The

tip of each prong has been sharpened to make it easier to push the sensor into the soil.

Be careful with the sharp tips!

4. Backfill the trench taking care to pack the soil back to natural bulk density around the

sensor body of the 5TE.

METHOD 2. VERTICAL INSTALLATION

1. Auger a 3-in hole to the depth at which the sensor is to be installed.

2. Insert the sensor into the undisturbed soil at the bottom of the auger hole using a hand

or any other implement that will guide the sensor into the soil at the bottom of the hole.

Many people have used a simple piece of PVC pipe with a notch cut in the end for the

sensor to sit in, with the sensor cable routed inside the pipe.

3. After inserting the sensor, remove the installation device and backfill the hole taking

care to pack the soil back to natural bulk density while not damaging the black

overmolding of the sensor and the sensor cable in the process.

Note: The installation method is from page 7 of 20435_5TE_Manual_Web.pdf.

7. Important Maintenance Instruction

Your device is a product of superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty

service effectively.

• Keep the equipment dry. Rain, moisture, and various liquids or moisture 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 can damage its detachable parts and electronic components.

• Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
