Features1Wide detection range, it can respond to the spectral range of 400?700nm, widely used in the research of meteorology, agriculture, air pollution and other fields. 2With an all?aluminum shell, its protection grade is IP67, which is compact and beautiful, making it more convenient for research. 3Equipped with a level gauge and an adjustment handwheel, it is convenient for on?site adjustment and can cope with research in different situations. 4Adopt high?quality cosine corrector, it uses wide voltage power supply DC 7?30V to ensure the cosine response standard. 5Proportional right?angle cosine, when there is light, it produces a voltage signal proportional to the strength of the incident radiation, and its sensitivity is lower than that of incident light. 6Adopting a specially treated dust cover, it can reduce dust absorption, effectively prevent environmental factors from interfering with internal components, and can more accurately measure photosynthetic active radiation. 7Using standard RTU 485 communication protocol, it can directly read the current effective radiation value, and the wiring method is simple.SpecificationItem Type: Solar Radiation SensorProduct Width: Approx.8cm / 3.1inProduct Height: Approx.5.8cm / 2.3inModel: RS-GH-N01-ALType: Type 485Power Supply: DC 7~30VMaterial: AluminumWeight: Approx. 308g / 10.9ozBasic ParametersPower Supply Voltage (Default)7V-30V DCExport Method485 (Standard RTU Protocol)Power Consumption0.06WRange Temperature-30-75Response Spectrum400nm~700nmMeasuring Range0-2500mol/sResolution1mol/sAccuracy2% (1000mol/s, 60%RH 25)Response Time0.1sLinear1%Yearly Stability2%Field Wiring InstructionsLine ColorDescriptionPower SupplyBrownPower Supply (7-30V DC)BlackPower NegativeOutputGreen485-ABlue485-BBasic Communication ParametersCode8-Bit Binary SystemData Bit8-BitParity BitNot SupportStop BitOne BitError CheckingCRC (Redundant Cyclic Code)Baud Rate2400bit/S, 4800bit/S, 9600bit/S Option, Factory Default 4800bit/sRS-Company CodeGH-Photosynthetically Active Radiation SensorN01-485 Output (Standard RTU)ALAluminum HousingUsing RTU communication rules, the format is as follows:Initial Structure: 4 Bytes TimeAddress Code:= 1 ByteFunction Code:= 1 ByteData Area:= N BytesIncorrect Version:= 16 Bytes CRC CodeEnd Structure: 4 Bytes TimeAddress Code: The address of the transmitter, which will be the only one in the communication network (factory default 0x01).Function Code: Command function commands from the host, this transmitter only uses function code 0x03 (read register date).Data Area: The data area is the specific communication data. Pay attention to the high byte of the previous 16-bit data.CRC Code: Double-Byte Correction Code.Troubleshooting:1. If the read value is 0, check whether there is a light source, and check whether the product protective cover has been removed.2. Please check whether the 485 wiring is correct and whether the wiring is reversed.3. Check whether the device address of the vehicle is wrong, or there are devices with duplicate addresses (the factory default is 1).4. Check whether the power supply meets the mark.5. The equipment is damaged.Product Maintenance:1. The shell of the product should be kept fluent and clean, and wipe it regularly with a soft cloth.2. Please regularly check whether it is level and whether the screws are loose.Package List1 x Sensor 1 x Connection Line 1 x English Manual
