The Ultrasonic Wind speed and Wind direction sensor
1 FOREWARD
Thank you for purchasing ultrasonic anemometer manufactured by Hongyuv. This device
without moving parts, free of maintenance and calibration on site. To achieve optimum
performance we recommend that you read the whole of this manual before proceeding with
use.
Hongyuv products are in continuous development and therefore specifications may be
subject to change.
The information contained in this manual remains the property of Hongyuv technologies and
must not be copied or reproduced for commercial gain.
2 INTRODUCTION
HY-WDS2E ultrasonic anemometer has advantage of light weigh, robust,no moving parts,
free of maintenance and calibration on site, simultaneously output wind speed and direction.
HY-WDS2E can be used in conjunction with a PC, data logger or other device, which has
compatible communication protocol with it.
HY-WDS2E can integrate optional modules to meet customers’ requirement without changing
its appearance. Such as adding barometric pressure sensor to measure air pressure, or
adding 3D module to measure vertical or horizontal amplitude of vibration.
The following options are available:
I. Windows XP/WIN7 based testing software II.Mounting kits($25)
which only support MODUBUS protocol(for free)
III. One meter USB to RS-232/RS-485 converter Cable (cost extra $25)
3 Working Principle
Measure the transmission time of ultrasonic sensors from sensor N to sensor S, and compare
with the transmission time of sensor S to sensor N. Similarly, compare the time of W to E and
E to W time. (N = north, S = south, E = east, W = west)
For example, if the wind blew from the north, time of ultrasonic from N to S will be shorter than
from S to N, and transmission time of it from W to E and E to W is the same. Through
calculating the time difference of ultrasonic transmission between two points, the wind speed
and direction can be calculated. This calculation method has nothing to do with other factors
such as temperature.

Communication troubleshooting
Foreword:The most effective and efficient way to test a sensor is creating a test environment
as simple as you can.
We understand that you may integrate our sensors into your systems by connecting them to
your data loggers, SCM platforms, data transmission units etc.
However, we don’t recommend you to test our sensors on those device at the very beginning.
The way recommended is to use an USB to RS232 or RS485 converter, and test
communication and response initially.
Following steps will help you understand if the sensor working or not.
Please notice that the essential precondition is correct wiring and suitable power supply.
Any under-voltage power supply will fail to turn on our sensors.
Any over-voltage power supply is harmful and can cause irreversible damage to our products.
Step 1~3 as below.
If Step 1 return gibberish. Please swap data cable DA/DB or TXD/RXD or re-confirm
configuration of serial port
If Step 1 has correct response, but Step 3 has none response. Please check if you wrongly
wire communication cable, it indicate that you can receive from sensor, but sensor didn’t
receive your command.
When the number of register you inquiry exceed existing registers within our sensor.
Following Error Code will be responded: 01834181 or 0183030131
Passing Step 1~3 means that communication test goes well, now you can move to next step,
we have a free software that workable on Window XP, WIN 7 for you on next page.

10 Installation Guidelines
The HY-WDS2E has been designed to meet and exceed the stringent standards listed in its
specification. Operating in diverse environments all over the world, HY-WDS2E requires no
calibration and adjustment whatsoever.
As with any sophisticated electronics, good engineering practice should be followed to ensure
correct operation.
Always check the installation to ensure the HY-WDS2E is not affected by other equipment
operating locally, which may not conform to current standards, e.g. radio/radar transmitters,
boat engines, generators etc.
·Avoid mounting in the plane of any radar scanner – a vertical separation of at least 2m
should be achieved.
·Radio transmitting antennas, the following minimum separations (all round) are suggested
VHF IMM – 1m
MF/HF – 5m
Satcom – 5m (avoid likely lines of sight)
·Use cables recommended by Hongyuv. If cables are cut and re-connected incorrectly
(perhaps in a junction box) then EMC performance may be compromised if cable screen
integrity is not maintained.
·Earth loops should not be created – wire the system in accordance with the installation
guidelines.
· Ensure the power supply operates to the HY-WDS2E specification at all times.
· Avoid turbulence caused by surrounding structures that will affect the accuracy of the
HY-WDS2E such as trees, masts and buildings. Ideally sensors should be mounted on the
prevailing wind side of the site.
The WMO make the following recommendations:
The standard exposure of wind instruments over level open terrain is 10m above the ground.
Open terrain is defined as an area where the distance between the sensor and any
obstruction is at least 10 times the height of the obstruction.
If mounting on a building then theoretically the sensor should be mounted at a height of 1.5
times the height of the building.
If the sensor is to be mounted on a mast boom, part way up a tower or mast, then the boom
should be at least twice as long as the minimum diameter or diagonal of the tower. The boom
should be positioned on the prevailing wind side of the tower.

11 Mechanical Installation
11.1 Land meteorological station installation
Location:Normally,HY-WDS2E is installed on a vertical
pole horizontally（refer to picture on the right side）
For indoor use, sensor can be installed anywhere to
measure wind speed and direction of corresponding
plane.
Orientation: orient north maker to north, then fix
sensor.
Note:Use a standard compass to find correct
geographic north direction then orient north marker to
it.
Installation: Pole should have three 3 equally spaced
holes for M5 screw 7.5mm lower than top of pole,put
cable(waterproof aerial plug) through pole.
Note: the user must have proper stress relief on the
cable.
Turn the plug and press it gently into the socket to
connect the plug to the HY-WDS2E outlet. When the
plug is connected, turn the outer sleeve clockwise and
lock the plug.
With 3 stainless steel screws, the HY-WDS2E can be
fixed to the mounting pipe (the screw has a maximum
installed torque of 4Nm)
Customers must ensure that the HY-WDS2E is installed in an open area so as to avoid
obstacles to airflow or turbulence in the surrounding buildings. Do not install HY-WDS2E on
the side of a high power radar or radio transmitter.

11.2 Installation on a vehicle or vessel
Location:Normally,HY-WDS2E is installed on a vertical pole horizontally ensure no other
things over 2 meters in the same horizontal plane to avoid obstruct the airflow or turbulence
from surrounding buildings.
Alignment: North marker of HY-WDS2E should be aligned to point to any other reference
direction –for example, the bow of a boat. There are two red arrows to help alignment as
shown below.
Note: Red dot is direction of internal electric compass,it’s also direction of boat’s bow,marked
as red dot on shell.
12 Clean
If dust is deposited on the instrument, you can scrub it gently with cloth coated with
(biodegradable) soft lotion. Do not use dissolved reagents, scrub carefully and avoid cutting
the surface of the instrument. If snow or ice is accumulated on the surface of the instrument, it
should be melted slowly and naturally. Never use tools to force it away.
12 After-sale service
The instrument does not have any moving parts and does not require routine maintenance.
If the user opens the instrument on its own or damages the safety seal on it, it will no longer
enjoy our quality assurance and calibration.
If anything goes wrong with the instrument, you may send the instrument to the authorized
agent of HongYuv.
13 Instrument Return
If the instrument needs to be returned, please carefully pack the instrument in the original
package and deliver it to the authorized agent of the Hongyuv with the detailed explanation of
malfunction.

Communication Protocol
MODBUS Protocol - RTU Mode.
Protocol Description
MODBUS protocol defines a simple protocol data unit(PDU) independent from basic
communication layer.
Figure 2. Commonly used MODBUS frame
MODBUS has two transmission mode:RTU and ASCII.
Our sensor adopts RTU mode.
1. RTU transmission mode
When controllers are setup to communicate on a Modbus network using RTU (Remote
Terminal Unit) mode, each eight-bit byte in a message contains two four-bit hexadecimal
characters. The main advantage of this mode is that its greater character density allows better
data throughput than ASCII for the same baud rate. Each message must be transmitted in a
continuous stream.
RTU Mode serial bits
Modbus RTU message frame
CRC Check
RTU Mode has Cyclical Redundancy Checking(CRC) on all content of message, no matter if
there is an odd-even check or not.
CRC check code is a 16 bits value composed by two 8 bits value and added as tail of
message. After calculation, lower byte first then high byte. CRC higher byte is the last byte of
message.

The Ultrasonic Wind speed and Wind direction sensor
The CRC check code is calculated by sender. Receiver will recalculate CRC check code and
compare it with CRC code received, if they are different, then there is an error happen during
transmission.
MODBUS communication Mode
Data Coding
MODBUS use ”big-Endian” to indicate address and data, which means when there is several
bytes be sent out, the most significant bit is sent and received first.
Eg.
