FainWan 3Pcs High Sensitivity Microphone Sensor AVR PIC Sound Detection Module for Ar-duino
The module has 2 outputs: AO, analog output, real-time output microphone voltage signal.
DO, when the sound intensity reaches a certain threshold, it outputs high and low level signals, [threshold-sensitivity can be adjusted by potentiometer].
There are 3mm mounting screw holes, which are powered by a 5v DC power supply..
There is an analog output with a threshold flip level output.High sensitivity microphone with high sensitivity..
There is a power indicator and the comparator output has an indicator..
Package include: 3Pcs High Sensitivity Microphone Sensor.
The LM2903P devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages.
Single-supply or dual supplies Wide range of supply voltage Maximum rating: 2 V to 36 V.
Low supply-current independent of supply voltage: 200 µA per comparator, Output compatible with TTL, MOS, and CMOS.
Common-mode input voltage range Includes Ground, Low output saturation voltage.
Differential input voltage range equal to maximum-rated supply voltage: ±36 V.
