Data Description

Protocol Communication

• The protocol used follows a data format like Modbus-RTU. It enables devices to actively report or request data.
• All communication must be converted to base64 format before transmission.
  NOTE
  The sample protocol provided only uses the original HEX format data. However, it is important to always remember to convert the content to base64 format before communication by default.

Protocol Command Format
All contents are arranged with high bytes first, followed by low bytes. Listed in the table is the protocol format.

Where:

• ADDR – Address
• CMD – Function code
• LEN – Data length
• DATA – Data content
• CRC – Cyclic redundancy check

Command Details
The tables display command definitions and sensor data reports, including both real-time and historical data formats.
NOTE
The address code is fixed at 0x01.

• CMD Definitions
  CMD| Description

• Historical Data Format Description

• • The following is an example of a complete historical data reporting format for sensor data:
    01 41 25 00 5C 77 88 B6 00 05 2F C2 9A 00 00 4E 2F C2 9A 00 00 4E 2F C2 9A 00 00 4E 2F C2 9A 00 00 4E 2F C2 9A 00 00 4E 48 8C

First set of sensor data

| Bytes 1–3: 0x2FC29A

·      Represent temperature and humidity

·      Temperature: 0x02FC (high 12 bits) 1

·      Humidity: 0x29A (low 12 bits) 2

Bytes 4–5: 0x0000

·      Reserved bytes

·      Don’t carry any data.

·      Optional, none in this example. Byte 6: 0x4E

·      Represents the battery level

17 – 22| Second set of sensor data| The same format as the first set.
Every 6 bytes is

a set of sensor data.

| LoRa: One frame of

historical data has up to 5 sets of sensor data.

| The same format as the first set.
41 – 42| Check code| 0x488C

• The temperature value is forward offset by 500. To get the actual temperature value, subtract 500 from the byte value of 0x02FC, equating to 264. However, the reading is expanded ten times, implying that the actual temperature of 264 is divided by ten.

  * The humidity value is expanded ten times to get the actual value.

  * The timestamp of each set of sensor data must be calculated based on the starting timestamp and data acquisition interval. In the previous reference data, the acquisition time for the set of sensor data is as follows:
  * First set: 0x5C7788B6
  * Second set: 0x5C7788B6 + 0x0005 (data acquisition interval)
  * Third set: 0x5C7788B6 + 0x0005 + 0x0005
  *  **Real-Time Data Format Description**
  * The following is an example of a complete real-time data reporting format for sensor data:

  ---|---|---
  1 time in total| 0x01| The default setting.
  1 time a day| 0xFE|

• Start and End Time

• The start and end times are offset in minutes, with 0:00 as the base point. For example, a time of 7:00 to 10:00 corresponds to 420 to 600 minutes.

• If the period is a full day, set the start and end times to the same value of 0. The predefined values indicate that the entire day has been covered.

• Value Setting

• To convert the temperature value to its actual reading, offset the value forward (subtract) by 500, then expand (multiply) by 10. However, for humidity, multiply the given value by 10.

• Unit description:

• Temperature: °C

• Humidity: %RH

• For example, if the temperature remains above 26 degrees Celsius for the entire period, the hexadecimal value would be: 01 42 0C 07 01 00 00 00 00 00 00 02 F8 23 E4.

• Configuration Settings
  To configure the interval settings, set the values as follows:

  • Data reporting interval: 1 hour
  • Data acquisition interval: 15 minutes
  • Fill in the unused items with 0 and send: 01 47 09 00 3C 03 84 00 00 00 00 00 28 5E
