Electret Microphone Sensor
The electret microphone provides a simple solution to use your surroundings as a sample source. The board features a little trimmer to adjust the gain of the microphone pre-amplifier. Use a little screwdriver to adjust the gain according to the printing on the sensor board. It‘s preferable to adjust the signal level with the trimmer first and only use the level pot of the analog signal interface as a second adjustment stage. The electret microphone has an omnidirectional directivity and is capable of capturing the whole frequency spectrum from 20 to 20000 Hz. The electret microphone is best be used with the ANALOG IN of the Field Kit’s Sensor Interface.
