Analog Output Sound Sensor Module Noise Sensing Detection Size | Электроника

Analog voltage signal output sound sensor

Functional description: it can detect sound size, sound, whistle, and sound intensity. But the special frequency can not be identified.

Characteristic:

1: the linear analog output can be directly output, when AD is collected, it is more convenient to solve a lot of customers, directly collect the pain of the waveform. It can also be used directly as a decibels sensor.

2: high sensitivity, the pro test, in a closed environment, normal speech can be detected within 10 meters.

3: a wide range of voltage, this design of the module, the power range from 5-----24V.

After the detection of sound output 0, no sound output 1, sensitivity can be adjusted by the potentiometer, clockwise and counter clockwise.

Interface definition:

1. G: land

2. V: power input range: 3V-24V.

3. DO: digital output, 0 or 1 (only to determine if there is no sound, and can not output digital data).

4. AO: sensor analog output range: 0V to (VCC minus 1.7). For example, the power supply 5V, the maximum output voltage is 5-1.7=3.3V
