1. Introduction
R718PB15A is a Class A type device based on the LoRaWAN protocol.
R718PB15A is connected with soil sensor (RS485 type)
As detectors for soil moisture, temperature, electrical conductivity, the values collected by the sensor are 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.

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.

5. Data Report
The device will immediately send a version packet report along with an uplink packet including soil moisture, soil temperature and soil electrical
conductivity values.
The device sends data in the default configuration before any configuration is done.
MaxTime : Max Interval = 60 min (default)
MinTime : None
Note:
(1) The device report interval will be programmed based on the default firmware which may vary.
(2) Mintime and ReportChange are not supported by R718PB15A (Invalid configuration)
(3) Report cycle will be based on Report Max Time period when sending data packet.
(4) Data packet: soil moisture, soil temperature and soil electrical conductivity
(5) It would take about 20 seconds for the soil sensor to sample and process the collected value if you were to manually trigger the device by
pressing the button, please be patient.
Data report configuration and sending period are as following:
(1) Configure device parameters MaxTime = 1min
Downlink: 01580000003C0000000000
The device returns:
8158000000000000000000 (Configuration succeeded)
8158010000000000000000 (Configuration failed)
(2) Read device configuration parameters
Downlink: 0258000000000000000000
The device returns:
82580000003C0000000000 (device current configuration parameters)

6. Installation
Method1. 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. Backfll the trench taking care to pack the soil back to natural bulk density around the sensor body of the soil sensor.
Method2. 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.
Cleaning And Maintenance
The EC measurement is very sensitive to the presence of nonconducting contamination on the screws, especially at high EC. The most common source
of contamination is skin oil from handling the screws with bare hands.
Use the following steps to clean the sensor:
1. Clean the screws using a mild detergent such as liquid dish soap and a nonabrasive sponge or cloth.
Note:
Avoid detergents that contain lotions or moisturizers.
2. Rinse the sensor and screws thoroughly with tap or DI water.
Do not touch the screws without gloved hands and never contact the sensors with any source of oil or other nonconducting residue.

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.
• Do not store in a 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
• Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may also explode.
All of the above suggestions apply equally to your device, battery and accessories.
If any device is not working properly.
Please take it to the nearest authorized service facility for repair.
