Feature:
1. Using standard RTU 485 communication protocol, it can directly read the current total solar radiation value, and the wiring method is simple.
2. High measurement accuracy, using pyroelectric sensor elements, short response time, small error, small temperature compensation, and more accurate measurement within the range.
3. The pyroelectric total solar radiation transmitter has beautiful appearance, small installation space, and the range reaches 0.3~3μm.
4. The light transmittance is as high as 95%, and the transparent double‑layer glass cover has good sensitivity and special surface treatment to prevent dust adsorption.
5. Products are widely used in solar energy utilization, meteorology, agriculture, building materials aging and air pollution departments to measure solar radiant energy.

4. Data frame format definition:
Using RTU communication protocol, the format is as follows:
Time for initial structure ≥ 4 bytes
Address code = 1 byte
Function code = 1 byte
Data area = N bytes
Error check = 16-bit CRC code
End time structure ≥ 4 bytes
Address code: The address of the transmitter, which is unique in the communication internet (factory default 0x01).
Function code: Command function instruction issued by the host, the transmitter can use function code 0x03 (read register data) and 0x06 (write register).
Data area: The data area is the specific communication data. First, pay attention to the high byte of the 16-bit data!
CRC code: double-byte check code.
5. Troubleshooting
1. If the reading is 0, check whether the protective cover of the product has been removed and whether there is sunlight
2. Please check if the 485 wiring is correct
3. Check whether the power supply meets the sign
4. Equipment damage
6. Product Maintenance
1. The glass cover should be kept smooth and clean, often wiped with a soft cloth or fur
2. There should be no water in the glass cover. If you encounter long-term weather such as heavy rain, snow, ice, etc., it is recommended to cover
3. It is recommended to check whether the desiccant in the dryer is damp regularly. The specific manifestation is that orange has turned into a dark color. If this happens, the desiccant should be replaced in time, or the desiccant should be taken out and dried and reused
4. After the equipment has been used for more than two years, the sensitivity must be recalibrated by the manufacturer or measurement department
