ESP-32 or ESP8266 Remote listener

(1/1)

sairfan1:
Hi I want to build a project where i can setup ESP module with mic and listen to device remotely from my Android phone.
I want to know if there are some modules available with complete hardware and any example libraries?

Yeah you can find such ready made module on ebay and aliexpress quite easily and you can also design them on your own. You will need NodeMCU module which used ESP8266 and can send the data on your mobile App.

sairfan1:
Does NodeMCU has builtin mic? I was looking for some module who has MIC pre builtin, I was not able to find such, if NodeMCU has one i will check again.

Thanks

jackthomson41:
No it doesn't has a builtin MIC on the chip, you have to interface MIC Jack with NodeMCU.

You should also have a look at Raspberry Pi which has the MIC jack on it but may be it will be too complex/expensive for the project.
