PGA460: Anemometer with 3 ultrasonic sensor pairs

Florian Möller
Prodigy 20 points
Part Number: PGA460
Other Parts Discussed in Thread: MSP430FR6043, EVM430-FR6043

Tool/software:

Hello
We are developing an anemometer consisting of 6 ultrasonic sensors, each consisting of 3 pairs of ultrasonic sensors. The sensors are to be used as transmitters and receivers in both directions to determine the wind speed. Can you tell me if I can implement this case with the PGA460 and how the ultrasonic sensors have to be wired to use them both as a pair in both directions?
Best regards,
Florian

    Hi Florian,

    Thank you for your question. For flow rate applications(upstream and downstream) such as an anemometer application we typically recommend the usage of the EVM430-FR6043.  The MSP430FR6043 is well suited to these designs as it offers 2 channels for determining delta ToF between 2 transducers.  You would need to use multiple devices or a mux for 3 pairs of transducers.  See the application brief below regarding high resolution anemometer.

    I do not directly support the EVM430-FR6043 so if you have any specific questions about this device feel free to make another post for this device specifically in the MSP430 forum. I hope this helps provides some guidance.
