Q: Does this work with TRRS aux cord? Also, can I use my headphones mic on the TX bluetooth transmitter with the TRRS aux cord?

elchal-li Thisis transmitter only. You can plug it on the line out connector, and listen to the music via Bluetooth on your BT headphones. It doesn't matter you have or not a microphone, because it will not be connected.

Q: Can the signal generated be plugged to a regular speaker?

demandé par FMK sur 2018-11-27 18:14:19

elchal-li You probably won't hear anything as the signal is too weak to power the speaker.

elchal-li If you see the schematic, you can drive a relay with the sensor and a transistor. Then you can use the normally closed contact to manage the light as you say.
