Hello,
Myself Neel Patel. I am in germany and working in Hahn-Schickard-Gesellschaft für angewandte Forschung e.V.. For one project work, we are using your product ICS- 40300 MEMS microphone. Earlier it was working perfect but now it is not working properly. So i want to ask you how to solve this problem. We did a lot of experiments with that and it was working very good but we do not understand what is wrong with microphone. We connected it to R&S UPV audio analyser directly for measurement and for power supply we used arduino or MSP. Now we are doing the same what we did in the past but it is not working. And second thing is, during measurement there is Hz frequency in every measurement. why and from where it is coming we do not know. If possible please help us. Your suggestions will be very helpful for us.
Thank you for your time and consideration.
Best regards
Neel Patel
Do you have a mesh on top of the microphone port to protect dust or water in getting into the microphone?
