Measuring Wind Speed & Direction with Ultrasonic Anemometer & Arduino

hi everyone welcome to how to Electronics in one of my earlier videos I explained about the mechanical anemometer from Adafruit this anemometer was able to measure the wind speed which was successfully displayed on OLED display today's video is not about any type of mechanical anemometer rather we will take a look at the ultrasonic anemometer from renke this anomometer does not have any moving Parts rather it uses ultrasonic principles to measure the wind speed as well as Direction in this tutorial we will go through the design and specification of this ultrasonic anemometer sensor this sensor is based on the rs-485 protocol hence we will use the max 485 module to interface the center with the Arduino board the animal meter will measure the wind speed and direction while placed in a windy Zone the speed and direction can be easily displayed on LCD display I gestured this animal major for a long period of time and found out it is highly accurate and performs better than mechanical anemometer so let's get started to find out more about this Center [Music] [Music] this video is sponsored by Altium 365. the Altium 365pzen Electronics product design platform that unites PCB design mcad these are management and teamwork with Altium 365 you can do the PCB designing task you can share your project over a Wi-Fi review purposes interact with mechanical designer for mechanical design it also provides centralized cloud storage it helps you with components management is it has the fastest search engine it can also allow your team to work together on a single product finally you can send your design to a manufacturing unit to get started with the free trial check the first link in the description welcome back again let's see how the ultrasonic animal meter Works ultrasonic anemometer uses ultrasonic wind measurement technology to measure wind speed in meters per second with low startup speed also it can measure a full 360 degrees of wind direction the ultrasonic time of sight principle is used to calculate the wind speed and direction the opposing sets of change stations alternatively send and receive ultrasonic pulses to each other in still air these pulses transmit at the same speed the wind speed affects the scent risky patterns of the pulses the pulses in the direction of air movement will reach the opposing transducers more rapidly while they pulses into the wind will be delayed the stronger the prevailing wind the more prominent the effect will be this is the ultrasonic anemometer from renkir this anomometer is an Innovative device engineered for the precise outdoor measurement of wind speed and direction it stands out for its compact design absence of movable parts and high production level making it accepts Nelly durable and suitable for hearts environments and generally the animal meter uses low powered Zips giving its power consumption Aid an efficient 0.12 what say this internal circuitry the engineering involved in this is highly appreciable the sensor operates at 10 to 30 volt DC power supply it can measure the wind speed from 0 to 40 meters per second with a resolution of 0.01 meter per second similarly it can measure wind direction from 0 to 360 degrees with a resolution of 1 degree this product adopts the standard modbus RTO 485 communication protocol which can directly read the current total solar radiation value it's shown here the output mode is rs-485 with a 4 to 20 ma sensor response it has four wires VCC gnd Iris 485a and rs-485 B to rate the wind speed and direction value using this sensor we need the following components I have used Arduino nanobot since the sensor output is RS 485 we need a modbus rtu module this is the max 485 module from Maxim integrated that can be easily interfaced with the mode was centered and a microcontroller to display the value I have used a 16 Cross to I Square C L Series display update board is required as well for prototyping and assembly few jumper wires are needed for the connection for Supply Power you may use a 12 volt battery a DC power adapter or any other power supply here is the connection diagram for this project all the connection between Arduino Max 485 and anemometer are preferably defined I made the same Connection in the breadboard as per the circuit diagram to power the hardware I used a 12 volt lead acid battery then I developed the sample code to read the center values from the manufacturer dataset I got to know how to rate the sensor value as a the inquiry frame and the response is perfectly explained here I will display the wind speed and direction values in serial monitor I placed the sensor behind my house to check the wind speed then I uploaded the code to the Arduino nanoport after uploading the code the serial manager shows the wind speed and direction value as 0 initially the wind is not blowing at all and the speed of air is very slow currently I waited for some time and the wind speed was displayed in kilometers per hour and direction in degrees perfect job now I added 6 string cross to I Square C LCD to the project is I wanted to show the wind values on LCD instead of Serial monitor then I made some modifications to the code finally observate the modified code again so as you can see the LCD is displaying the wind values as expected the wind speed value changes is for change in wind speed and directional value Remains the change are same that's all from the video part today you can purchase this sensor from renkates official website more details on the sensor can be found here as well the details documentation of the project has been published on our website how to electronics.com you may go through all the details specifications working schematics coding results and demonstration in case you have any doubts you can ask us questions in the comment section below thank you so much for watching the video see you in the next video
