Protocol Description

LoRa Protocol

If you need to connect the LoRa protocol, please contact our technology.

MODBUS Protocol

1. Definition of holding register address

Address	Register information	Operation	Remarks
0x1000	MODBUS address	read/write	1~254, default 01,0 and FF are broadcast addresses
0x0001	Temperature	read only	Resolution: 0.01℃ Range: -40~125℃ Accuracy: ±0.2℃

0x0002	Humidity	read only	Resolution: 0.1%RH

2、Example

Read the temperature of device address 0x01

Query Frame:

Address code	function code	Start address	Data length	Check code low position	Check code high position
0x01	0x03	0x00 0x01	0x00 0x01	0xD5	0xAC

Reply Frame:

Address code	function code	returns the number of valid bytes	Temperature value	Check code low position	Check code high position
0x01	0x03	0x02	0x00 0x12	0x38	0x49

Temperature: 0012H(hex)=18=>temperature=18
