All sensors operate according to simple physical principles and output their measured values as electrical signals that the microcontroller can evaluate.\u003c\/p\u003e \u003cp\u003eThe individual sensors connect to the controlled board via jumper wires and sockets. Since the sensors have different voltage-range and interface requirements, check which levels your own board provides before connecting them.

The audio signal is connected directly to the IC input, and the device's supply voltage must be between 9 and 15 V.

The ten LEDs cover a range of approximately −20 to 0 dB.\u003c\/p\u003e \u003cp\u003eTypical applications include simple level monitoring for portable audio devices, monitoring microphone inputs in recording setups, and providing visual feedback in DJ equipment and mixing consoles.
