Hi,
I am developing a system which has an electret microphone in it. The microphone gives an output voltage in the range of few millivolts. I am using wires to transmit the microphone output to an amplifier circuit and the amplified output goes to the programming software through a microcontroller. I am looking to eliminate the wires and turn the system into a wireless one. I am new to this. Could you please help me with this ?
Thanks,
Aishwarya
If you want a wireless microphone, then you need to do some design work. There are no purpose made shields to do it.
The mic output is very low so needs amplification to get the signal above the noise in the electronics.
Please tell us what you are trying to achieve.

Wireless microphones are a very specialised area, and the frequency ranges for then differ depending on which
country you are in.
They usually use wideband FM for the analog types and QPSK for the digital ones.
Whats the aim of the project.
What audio frequency range and signal to noise ratio are you trying to achieve?
Thank you for your responses. I am using POW-1644L-LWC50-B-R microphone. The output will go to an amplifier circuit. I will either have to transmit the unamplified microphone output voltage to the amplifier circuit wirelessly via arduino with bluetooth module or some other wireless protocol or I will have to connect the amplifier circuit to the microphone and transmit the amplified output wirelessly to a computer.
Hi, are you wanting to transmit digital audio waveform data, or average sound level readings?
