Sound Detection Module Sensor for Intelligent Vehicle Compatible With Arduino is a Single channel signal output Sensor. The output is effective to the low-level sound signal with good fidelity, When there is sound, outputs low level and signal light.
sound detection module has two outputs:
1. AO, analog output, real-time output voltage signal of the microphone
2. DO, when the sound intensity reaches a certain threshold, the output high and low signal
- there is a mounting screw hole of 3mm.
- 5v DC power supply
- With analog output
- there are threshold level output flip
- the highly sensitive microphone and high sensitivity.
- Power indicator light
- the comparator output is light
