HIGH ACCURACY MEASUREMENTS: With its core device being a high accuracy photovoltaic component, the sensor boasts superior stability and accuracy, ensuring reliable radiation readings. 3. QUARTZ GLASS COVER: The sensor is equipped with a glass cover, expertly crafted through optical cold machining. This effective shield guards against environmental factors, sustaining the sensor's optimal performance. 4. PROTECTIVE DESIGN: The sensor comes with a cover that safeguards the device during transport and in extreme weather conditions. For use, the cover is simply rotated and unscrewed, demonstrating the sensor's user friendly design. 5. MULTI FUNCTIONAL: The solar radiation sensor is capable of measuring total solar radiation within a spectrum range of 0.3 to 1.1μm. Additionally, by positioning the sensor surface downwards, it can detect reflective radiation. The use of a shadow part also enables the device to measure scattered radiation. Specification: Item Type: Solar Radiation Sensor Line Color: Red, Output Voltage: Positive Power Supply Line Color: Green, Output Voltage: Negative Power Supply Line Color: White, Output Voltage: Signal Power Supply: 5V Output: 0-2.5V Formula: F = V / 2.5 x 1500 Dimensions: Approx. 65x52x49mm / 2.56x2.05x1.93in, Bottom Hole Distance: Approx. 57mm / 2.24in Material: Aluminum alloy Spectrum Range: 300-1100nm Resolution: 1W/m2 Measurement Range: 0-1500W/m2 Sensitivity: 7-14μV/W•m-2 Accuracy: ±5% Load Capacity: Current output impedance RL ≤ 250Ω, Voltage output impedance RL ≥ 1KΩ Response Time: <5s Cosine Response: <±10% (Sun altitude angle 10°) Nonlinearity: <±5% Annual Change Rate: <±5% Operating Environment: Temperature -40°C-60°C, Humidity ≤ 100%RH Power Consumption: 0.48W Modbus CRC Check Steps: 1. Preset the 16 bit register to hexadecimal FFFF, call this register the CRC register 2. Dissimilarize the first 8 bits of data with the lower bit of the CRC register and put the result in the CRC register 3. 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; 4. If the lowest bit is 0: repeat step 3 (shift again) if the lowest bit is 1: the CRC register is XOR with 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 through 5 for the next 8 bit data The final CRC register obtained is the CRC code (the CRC code obtained is low before high) Fault Resolution: The meter displays an incorrect value when outputting. Correct data may not be acquired due to wiring problems or communicating serial port failure. Please check whether the wiring is correct and firm, whether the serial port is occupied, and whether the serial port setting is correct; Weight: Approx. 298.00g / 10.51oz.
