Noise Click is a mikroBUS\u2122 add-on board with noise detecting circuitry. It enables you to set a noise detection threshold for alarm systems, environmental monitoring or data logging.<\/p>\n\n
When the volume of ambient sound reaches the set threshold, an interrupt is triggered.\nThe most important parts of the circuit are the microphone, an RMS-to-DC converter, two dual rail-to-rail Input\/Output 10 MHz operational amplifiers, and a 12-bit digital-to-analog converter (DAC).<\/p>\n\n
The 12-bit DAC provides the reference voltage \u2014 the noise threshold \u2014 for the comparator. You set the exact level through the SPI interface. The threshold should be configured through trial and error (4096 discrete values to select from).\nBeside SPI, EN and OUT pins provide additional functionality.<\/p>\n\n
The board works on a 3.3V power supply.<\/p>\n\n
