01GARDENING TOOLS
Precision in every photon
A compact instrument of aluminum and quartz, this sensor sits quietly on a rooftop or research station, translating invisible light into readable data. Its cool metal casing feels solid and deliberate, designed to withstand the elements while remaining unobtrusive.
Engineered for meteorology, energy analysis and agriculture, it captures total solar radiation with high accuracy. The device suits professionals who require reliable readings from a stable photovoltaic core, offering a clear signal for complex environmental studies.
02MATERIALS
Quartz glass and aluminum alloy
The sensor’s face is protected by a quartz glass cover, crafted through optical cold machining to shield the internal components from environmental stress. This material choice ensures the device maintains optimal performance over time. The body itself is formed from aluminum alloy, providing a robust structure that balances weight against durability.
04DESIGN
Protective cover and simple access
A dedicated cover safeguards the device during transport and exposure to extreme weather. To begin measuring, the user simply rotates and unscrews this shield, revealing the sensitive surface beneath. This mechanical interaction is straightforward, removing friction from the setup process and ensuring the sensor is ready for immediate deployment.
05DETAILS
Compact dimensions and wiring
Measuring approximately 65x52x49mm, the sensor is small enough for tight installations yet substantial enough to feel secure. The bottom hole distance is roughly 57mm, aiding in mounting alignment. Three wires indicate function: red for positive power, green for negative, and white for the signal, simplifying integration into larger systems.

About this product
Preset the 16 bit register to hexadecimal FFFF, call this register the CRC register
Dissimilarize the first 8 bits of data with the lower bit of the CRC register and put the result in the CRC register
Check the lowest bit by shifting the contents of the register one bit to the right (towards the lower bit) and filling the highest bit with a 0;
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)
Please check if the packaging is intact and verify if the product model matches the selected model2. Do not connect the wires while they are energized. Only power on after checking for correctness
The length of the sensor wire may affect the product output signal. Do not make arbitrary changes during use
The sensor is an accurate device. Users should not disassemble it, use pointed objects, or damaging liquids to touch the sensor surface to avoid damaging the product
