mode 1: Over-limit Alarm
Mode 2: under-limit alarm
mode 3: over/under-limit action
Illumination display value X1000 = current value as shown in figure 3.63, indicating the current illumination value of 3630 lux
- Press SET to enter upper limit threshold settings press” ” to select the position, press” “” V” to adjust the value mode 1,3, when the value is greater than the upper limit threshold relay 1 action upper limit threshold: the default value of 50000, the maximum value of 65000
- Press SET twice to enter the lower limit threshold settings press” ” to select the position, press” ” !” ” to adjust the numerical value mode 2,3, when the value is less than the lower limit threshold relay 2 action lower limit threshold: default 0, maximum 65000
- Press SET three times to enter the control return settings press” ” to select the position, press” ” “! ” ” ” to adjust the value of the default return difference 1000, the maximum 60000
- Press four sets to enter the control mode, press” ” to select the position, press”! “”” to adjust the numerical value rnode 1, above the upper threshold action mode 2, below the lower threshold action mode 3, above the upper threshold action/below the lower threshold action
Wiring instructions
In the case of broken wires, wire the wires as shown in the figure. If the
product itself has no leads, the core color is for reference.
How to use software?
Flower farming
Flowerfarming requires light management According to the light requirements of
plants
To cooperate with the sensor to control the illumination
GREEN HOUSE
Effective management with sensors Create a good light environment for crops
Promote better photosynthesis
Construction
Adevice for measuring levels of light intensity
Under certain circumstances
Strict illumination requirements are required

Communication Protocol
The product uses RS485 MODBUS-RTU standard protocol format, all operation or
reply commands are hexadecimal data. The default device address is 1 when the
device leaves the factory, and the module or NON-Recorder default baud rate is
9600,8,n,1 ,but data recorder default baud rate is 115200 .
- Read data (function code 0x03)
Inquiry frame (hexadecimal), sending example: query 1 data of 1# device, the upper computer sends the command: 01 03 00 00 00 01 84 0A.Address| Function Code| Start Address| Data Length| Check Code
---|---|---|---|---
1| 3| 00 00| 00 01| 84 0A
For the correct query frame, the device will respond with data: 01 03 02 00 79 79 A6 , response format:
| Address | Function Code | Length | Data 1 | Check Code |
|---|---|---|---|---|
| 1 | 3 | 2 | 00 79 | 79 A6 |
Data description: The data in the command is hexadecimal, take data 1 as an example, 00 79 is converted to decimal value as 121, assuming the data magnification is 100, then the real value is 121/100=1.21, Others and so on.
- Common data address table
For example, if the current state is too small, we want to add 1 to its real value, and add 100 to the
current value. The correction operation command is: 01 06 00 6B 00 64 F9 FD .Device Address| Function Code| Register Address| Target Address| Check Code
---|---|---|---|---
1| 6| 00 6B| 00 64| F9 FD
After the operation is successful, the device will return the information: 01
06 00 6B 00 64 F9 FD , after the successful change, the parameters will take
effect immediately.
