1. Introduction
LAS-604V2 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. The
temperature measurement is through PT100 probe. For forcing various requests of demand, LAS-604V2
supports two operation modes, mode A and mode B. Mode A is hourly report that temperature is reported or
recorded every hour. Mode B supports temperature measurement every 30 seconds, 1 minute or 2 minutes,
depending on setting. In addition, LAS-604V2 will retrieve date time for synchronous from server at boot up
which make sure the accuracy of report time period.

2. Installation
The first step to start to use LAS-604V2 is installing battery. LAS-604V2 can be opened by simultaneously
holding and pressing two places in red circle of following figure. A battery holder is inside LAS-604V2, as
Figure 2. The supply voltage of battery is 3V.

There is a wakeup button, SW1, which is used to wakeup LAS-604V2 when it enters deep sleep mode.
Figure 3 Wakeup Button
There is a jumper inside LAS-604V2 for selecting operation mode of LAS-604V2. Figure 4 is an example which
sets LAS-604V2 to Mode B.

3. Device Setup
Device Activation:
First step is created a node on LoRaWAN Network Server. The Device EUI, Application Session Key, and
Network Session Key will get from product supplier. Application must set to LAS-602/4 and Activation and
LoRaWAN Class should be set to ABP and Class A separately.
Note: Due to LAS-602/4 sending periodically report at each clock, the downlink window is recommended
to set to RX2 for preventing from data collision.
Figure 5 Device Activation
Gateway Notice:
Another notice is that make sure the Gateway frequencies setting is same as LAS-604V2. And the address of
packet forwarder setting must be set to LoRaWAN network server correctly.

4. Report and Data Format
4.1. Mode A
LAS-604V2 reports temperature and alarm through LoRaWAN’s uplink. By default, LAS-604V2 will send a
temperature report every hours. In addition to temperature report, LAS-604V2 will read temperature every 5
minutes by default and compare read value with allowable temperature range. If read temperature is out of
allowable temperature range, an alarm will be sent. Besides, the allowable temperature range can be set by
downlink command.
Except temperature and status report, a LoRaWAN MAC command, DeviceTimeReq, is sent from LAS-
604V2 to server for time synchronization. Figure 8 depicts the entire sequence from power on.
Figure 8 LAS-604V2 Sequence Diagram
There are 3 uplink will be sent by LAS-604V2, temperate report, status report and temperature alarm. The
format of these 3 reports are described at following.

4.1.1. Temperature Report
Temperature report is sent by LAS-604V2 at every predefined period. The period can be changed by downlink
command. The length of temperature report depends on how many temperature records in a single report.
4.1.2. Status Report
Status report is sent by LAS-604V2 at power-on and when LAS-604V2 getting downlink command.
4.1.3. Temperature Alarm
Temperature alarm is sent by LAS-604V2 when the read temperature is out of allowable range.
4.1.4. Downlink Setting Command
Downlink setting command is sent by server to LAS-604V2 for changing period of temperature report and
detection. Once LAS-604V2 getting a downlink command, it should send back a status report for
confirmation.

4.2. Mode B
There is one uplink data type of LAS-604V2 for reporting temperature records and 3 downlink data type for
remote settings whose are manually offset setting, interval time/record period, and single mode (Mode 1)
setup. The formats of these data types are described at following section.
4.2.1. Temperature Report (Uplink)
Temperature report is sent by LAS-604V2 at every predefined period. The period can be changed by downlink

4.2.2. Remote Setting Command (Downlink)
Remote setting command is sent by server to LAS-604V2 for changing offset by manually, interval time and
record period, and single mode activate. Once LAS-604V2 getting a downlink command, it should send back a
status report for confirmation.
In Server downlink page, selecting the specific device and port 15 for setting. The Downlink Payload rules and
examples are shown below:

Example OP 1: The report temp. is 28.0°C, and need to adjust to 25.0°C for calibration.
The offset value setting is calculated as: (25.0-28.0) * 10 = -30, then transfer -30dec to Hexadecimal data
type, 0xFFE2. Finally, the downlink payload is 01FFE2
Example OP 2: The measure time is need to adjust to 60 sec (Mode 3).
The offset value setting is calculated as: 60/ 10 = 6, then transfer 6dec to Hexadecimal data type, 0x0006.
Finally, the downlink payload is 020006. Therefore, the report period will also set to the mode 3
behavior.

temperatures
» Areas exposed to static electricity
» Areas exposed to strong magnetic fields
» Areas exposed to water leakage
» Areas subject to condensation or wet areas
» Areas exposed to excessive vibration » Areas exposed to excessive smoke, dust or dirt.
CAUTION Other Precautions:
» Use the unit in the specified operating environment. Do not use it for any purpose other than for which it
was designed.
» Condensation may occur inside the case when a unit is moved from one environment to another where
there is a great difference in temperature.
» Do not use the unit in wet areas or places exposed to water such as bathroom.
» Do not insert any foreign objects into any of the units' jacks.
» If the unit gets dirty, wipe it with a clean cloth.
» Make sure to remove dust and dirt from plugs of any cables.
» Battery terminals may provide insufficient contact due to age or vibration. This may lead to data loss.
» Please note that this document has been written based on the presupposition that details about contracts
with an Internet provider, specific network environments and the set-up of any other necessary equipment to
enable network connection has already been taken care of by the User and that connection has been
confirmed as workable. Kiwi technology Inc. shall not be responsible for any damages which a contractor, a
user or a third party may suffer, whether direct or indirect, due to the inability to communicate or use
communication devices.
CAUTION Notices about Sensors:
» Do not connect any sensor to the unit other than those specified by Kiwi technology Inc.
» Make sure to use sensors within the measurement range indicated in the specifications for that sensor.

damage or malfunction.
» When the sensor is not to be used for a long period of time, please store it at normal temperature and

kiwitec Confidential Documentation 15
humidity.
» The included sensor is not water resistant. If the sensor gets wet, immediately remove the sensor from the
unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room
temperature before using it again.
» Do not use the sensor on the human body.
Temperature-Humidity Sensor
» If extremely severe temperature changes occur, it may result in large errors in humidity measurement. Once
the sensor's temperature becomes stable, the measurements will return to normal.
» The temperature-humidity sensors will with normal use experience losses in precision and sensitivity over
time due to degradation. If the sensor is being used in an unsuitable environment (smoky or dusty places) it
may be necessary to change the sensor sooner.
» Do not expose to condensation, dampness, corrosive gases, or organic solvents.
