RS232 Modbus Photoelectric Radiation Sensor High Accuracy Professional 9 to 30V for Meteorology Energy

1、Versatile Measurement Capabilities: The photoelectric sensor is capable of measuring solar total radiation within a range of 0.3-1.1μm. If the sensor is oriented downwards, it can measure reflected radiation. It enables scattered radiation measurements when coupled with a shading ring. 2、Excellent Accuracy: The core of this pyranometer solar radiation sensor is a highly accurate photosensitive element, ensuring superior stability and accuracy in measurements. 3、Excellent Environmental Resistant: This sensor comes with a quartz glass cover, precisely engineered through cold working optical techniques, which effectively mitigates the impact of environmental factors on its performance. 4、Protection Cover: The sensor includes a protection cover that safeguards it during transport, and protects the device from damage during harsh weather conditions. The cover needs to be unscrewed during usage. 5、Broad Applications: This photoelectric radiation sensor can be widely used in various fields such as meteorology, energy, construction, etc., showcasing its versatility and practicality.

Modbus CRC verification steps:
1. Preset a 16 bit register as hexadecimal FFFF, which is referred to as the CRC register;
2. Set the first 8 bit data to be different from the lower bit of the CRC register and place the result in the CRC register;
3. Move the contents of the register to the right by one bit (towards the lower 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: XOR the CRC register with polynomial A001 (1010 0000 0000 0001);
5. Repeat steps 3 and 4 until the entire 8 bit data is processed by shifting to the right 8 times;
6. Repeat steps 2 to 5 to process the next 8 bit data;
The final CRC register obtained is the CRC code (the obtained CRC code is low before high after).
Troubleshooting:
The instrument display value is incorrect during output. It may be due to wiring issues or conversation serial port failures that the correct data cannot be obtained. Please check if the wiring is correct and secure, if the serial port is occupied, and if the serial port settings are correct;

Note
1. Please check if the packaging is intact and verify if the product model matches the selected one;
2. Do not connect wires with power on. After the wiring is completed and checked for accuracy, power can be turned on;
3. The length of the sensor wire will affect the output signal of the product, so do not make arbitrary changes when using it;
4. Sensors are precise components, and users are advised not to disassemble them themselves, use hard objects or liquids contacting the sensor surface, in order to avoid damaging the product;
5. The protection cover should be removed when using the sensor;
