1. Introduction

R718CKAB: The temperature/humidity sensor and K-type thermocouple can respectively detect the temperature and humidity, and an

object's surface temperature. The temperature measurement range of R718CK is -40 °C to +375°C. R718CK has the

features of good linearity, larger thermal electromotive force, high sensitivity and stability. It should not be used in

sulfuric environments, reducing, oxidizing, and vacuum atmospheres, or weak oxidizing atmosphere.

R718CTAB: The temperature/humidity sensor and T-type thermocouple can respectively detect the temperature and humidity, and an

object's surface temperature. The temperature measuring range of R718CT is -40 °C to +125°C but it works more stably in

the range of -40°C to 0°C.

R718CNAB: The temperature/humidity sensor and N-type thermocouple can respectively detect the temperature and humidity, and an

object's surface temperature. The temperature measuring range of R718CK is -40 °C to +800°C, which is wider than other

types of thermocouples.

LoRa Wireless Technology:

LoRa is a wireless communication technology that adopts techniques such as long-distance communication and low power

consumption. Compared with other communication methods, LoRa spread-spectrum modulation techniques greatly expand the

communication distance. It is used in long-distance and low-data wireless communications like automatic meter reading, building

automation equipment, wireless security systems, and industrial monitoring control system. The features include small size, low

power consumption, long transmission distance, and anti-interference ability.

LoRaWAN：

LoRaWAN built LoRa’s end-to-end standards and techniques, ensuring 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 battery cover.)

Turn on

Press and hold the function key for 3 seconds until the green indicator flashes.

Turn off (Reset to factory setting)

Press and hold the function key for 5 seconds until green indicator flashes fast for 20 times.

Power off

Remove Batteries.

Note

1. When user removes and inserts the battery; the device should be off by default.

2. 5 seconds after power on, the device will be in engineering test mode.

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

(without factory resetting)

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

User is recommended to check the device verification information on the gateway or consult

your platform server provider.

Function Key

Press and hold for 5 seconds

Reset to factory setting/Turn off

The green indicator flashes 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 the setting value or the state changes, the device will send a

data report based on the Min Interval.

Low Voltage Warning

Low Voltage

3.2 V

5. Data Report

The device will immediately send a version packet report along with an uplink packet including temperature and battery voltage.

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

Default:

Max Interval: 0x0384 (900s)

Min Interval: 0x0384 (900s) (Automatically checking the current voltage every Min Interval)

BatteryChange: 0x01 (0.1V)

TemperatureChange:0x01 (1°C)

AirTemperatureChange: 0x01 (1℃)

AirHumidChange: 0x01 (1%)

Note:

1. The interval of the data reports might vary due to the firmware.

2. The interval between two reports must be the minimum time.

3.Please refer to the Netvox LoRaWAN Application Command and http://www.netvox.com.cn:8888/cmddoc for devices’ data

analysis.

Data report configuration and sending period are as following:

Tips

1. Battery Voltage:

The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.

Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.

The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v

2. Version Packet:

When Report Type=0x00 is the version packet, such as 01C4000A0B202005200000, the firmware version is 2020.05.20

3. Data Packet:

When Report Type=0x01 is data packet.

4. Signed Value:

When the temperature is negative, 2's complement should be calculated.
