This high sensitivity sound detection module detects sounds between 48 and 66 dB and has an analog as well as a digital output. The AO or analog output creates a real-time output voltage signal of the microphone, whereas the DO or digital output depends on the sound intensity and the threshold that has been set. voltage: 3.3 to 5 VDC outputs: one analogue + one digital output fixation: 1 mounting screw hole 3 mm 2 indicator LEDs: 1 power indicator + 1 comparator output indicator frequency response: 50 Hz - 20 KHz impedance: 2.2 K Ohm sensitivity: 48 - 66 dB operating temperature: -40 to +85°C dimensions: 44 x 15 x 10 mm weight: 4 g
