01GARDENING TOOLS
Precision for Solar Measurement
Mounted on a rooftop or within a weather station, this sensor quietly tracks the sun’s energy with quiet precision. Its compact form fits seamlessly into technical setups where data accuracy matters.
Designed for meteorology, energy, farming, and construction, it converts light into reliable signals via its high-precision photosensitive core.
02MATERIALS
Durable Aluminum and Quartz Glass
The sensor features an aluminum alloy body that withstands outdoor conditions, while a precision optical cold-worked quartz glass cover protects the internal element. This combination ensures stability against environmental variables, maintaining consistent performance over time.
04DETAILS
Versatile Mounting and Protection
Weighing just 0.35 kg in its carton, the unit is easy to handle. A protective cover safeguards the instrument during transport and bad weather, unscrewing easily for use. The bottom hole distance of approximately 57mm allows for secure mounting in various applications.

Highlights
- 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.

- 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);

About this product
Preset the 16 bit register to hexadecimal FFFF, call this register as CRC register;
Isolate the first 8 bit data with the lower bit of the CRC register and put the result in the CRC register;
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;
Repeat steps 3 and 4 until it is shifted right 8 times so that the entire 8 bit data is all processed;
The final CRC register obtained is the CRC code (the CRC code obtained is low before high).
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;
Please check whether the packaging is intact and verify if the product model matches the selection; 2. Do not wire when powered, only power on after checking the connection is correct;
The length of the sensor wire will affect the product output signal, do not change it randomly during use;
The sensor is a precision device, please do not disassemble, use sharp objects, or touch the sensor surface with corrosive liquids to avoid damaging the product;
