Can you suggest suitable circuit configuration for wireless output from ADXL 330z or other 3 axis MEMS accelerometers through blootooth
What application are you going to do. ADXL362 + ADUCRF101 could be the low power wireless acceleration transmission solution.
Thanks for the reply. I want to measure the 3 velocities of a moving object in a fluid medium. It may not be possible to have an projecting antenna. What are the alternatives?. Any suggestions on detailed circuitary? What is the requirement at the receiver end
You can use short time integration method to get velocity from accelerometer but normally, it is easy to be influenced by tilt variation. Tilt and acceleration due to motion are indistinguishable by the accelerometer, so you may also need gyro to detect the tilt angle. Of course, you can start with ADXL362 if your motion is pretty linear. Refer to the wireless communication in fluid medium vs. lands, it is different animal. From my study, underwater acoustic communication is more popular in fluid medium for wireless method, this is not my territory . Hope these can help a little.
Just a quick FYI, the ADuCRF101 is not relased yet, but if/when it is available for purchase you should see the pricing table appear at the bottom of the ADuCRF101 product page.
