Sound Detection Sensor Module Intelligent Vehicle For Arduino Raspberry Pi

Sound Detection Sensor Module Intelligent Vehicle For Arduino Raspberry Pi A sound sensor is defined as a module that detects sound waves through their intensity and converts it to electrical signals. The sound detection sensor module for Arduino detects whether the sound has exceeded a threshold value. Sound is detected via microphone and fed into an LM393 op-amp. The sound level set point is adjusted via an onboard potentiometer. When the sound level exceeds the set point, an LED on the module is illuminated and the output is sent low. Specifications: Operating voltage 3.3V-5V Outputs digital switching output (high and low levels 0 and 1 Operating current (Vcc=5V): 4-8mA Microphone sensitivity (1Khz): 52-48dB Microphone Impedance: 2.2KΩ Microphone Frequency: 16-20Khz Microphone S/N ratio: 54dB Signal output indication Single channel signal output Outputs low level and the signal light when there is sound) Package Content: 1 x Sound Detection Sensor UK Seller, quick dispatch. 1ST CLASS POST.
