Chapter 1 Product Introduction
1.1 Product overview
JXBS-3001-ZFS Total Solar Radiation Sensor
(Transmitter) is a sensor that can measure total solar
radiation with a spectral range of 0.3-3μm. If the
sensing surface is facing downwards, it can measure
reflected radiation, and a light-shielding ring can
also measure scattering radiation.
The core component of the radiation sensor is a
high-precision photosensitive element, which has good
stability and high accuracy. At the same time, a
quartz glass cover made of precision optical cold
processing is installed outside the sensing element to
effectively prevent environmental factors from
affecting its performance. The product can be widely
used in meteorology, energy, agriculture, construction
and other fields.

1.1 System framework diagram
This sensor can be connected and used alone, first use 12V DC power
supply Power supply, the device can be directly connected to a PLC
with a 485 interface, through
The 485 interface chip is connected to the microcontroller. The
single-chip microcomputer and PLC can be programmed through the
modbus protocol specified later to cooperate with the sensor. use
simultaneously
USB to 485 can be connected to the computer, use the sensor
configuration tool provided by our company to configure and test.

This product can also be used by combining multiple sensors on a 485
bus,
Please observe "485 Bus Field Wiring Rules" when performing 485 bus
combination
(See Appendix). In theory, one bus can connect more than 16 485
sensors
If you need to connect more 485 sensors, you can use a 485 repeater
to expand
Charge more 485 devices, connect the other end to the PLC with 485
interface, connect the MCU through the 485 interface chip, or use
USB to 485 to connect to the computer, and use the sensor
configuration tool provided by our company to configure and test.

Note: Please be careful not to connect the wrong wiring sequence,
the wrong wiring will cause the equipment to burn.
The factory default provides 0.6m long wire, customers can
extend the wire as needed or wire in order.
Note that there is no yellow line in the line sequence that may
be provided in some factory batches. At this time, the gray line is
equivalent to replacing the yellow line.

2.3 Product size and installation instructions
(1) Ensure that the mounting bracket is parallel to
the ground;
(2) Use M6 screws and nuts to fix the sensor on the
cross arm through the 2 mounting holes on the sensor;
(3) Please avoid disassembling the sensor during
installation.
(4) Please unscrew the protective cover above the
sensor when using it. In order to protect the sensor,
tighten the protective cover above the sensor when
it is not in use or during transportation.

Our company provides supporting "sensor monitoring
software", which can easily use the computer to read
the sensor parameters, and flexibly modify the device
ID and address of the sensor.
3.1 Connect the sensor to the computer
After the sensor is correctly connected to the computer via USB
to 485 and supplied with power, you can see the correct COM port
("My Computer—Properties"
—Device Manager — Port” to view the COM port).
