1、Function: Used to measure the total solar radiation in the spectral range of 0.3-1.1μm, if the inductive surface is down to measure reflected radiation, the shading ring can also measure scattered radiation. 2、High Precision: The core device of the radiation sensor is the high precision photosensitive element, which has excellent stability and high precision at all times. 3、Glass Cover: A quartz glass cover made of precision optical cold working is installed outside the induction element, which effectively prevents the influence of environmental factors on its performance. 4、Protection Cover: The protective cover safeguards the instrument during transportation, protect the instrument from damage in bad weather. Rotate to unscrew the cover when in use. 5、Versatile Application: Solar radiation sensor is suitable for a broad range of industries, such as meteorology, energy, farming, and construction.

For Modbus CRC checking steps :.
1. Preset the 16 bit register to hexadecimal FFFF, call this register as CRC register;
2. Isolate the first 8 bit data with the lower bit of the CRC register and put the result in the CRC register;
3. shift the contents of the register one bit to the right (towards the low bit), fill the highest bit with 0, and check the lowest bit;
4. if the lowest bit is 0: repeat step 3 (shift again) if the lowest bit is 1: the CRC register is iso-orthogonal to the polynomial A001 (1010 0000 0000 0001);
5. Repeat steps 3 and 4 until it is shifted right 8 times so that the entire 8 bit data is all processed;
6. repeat steps 2 to 5 for the next 8 bit data;
The final CRC register obtained is the CRC code (the CRC code obtained is low before high).
Trouble Removal:
The meter display value is incorrect when outputting. It may be due to wiring problems or comm serial port failure that the correct data cannot be acquired. Please check whether the wiring is correct and firm, whether the serial port is occupied, and whether the serial port setting is correct;
