Sound sensor module High sensitivity microphone amplifier whistle switch detection control sensor module
High sensitivity sound sensor
Sensitivity adjustable combinational circuit optimal collocation
The sound module is most sensitive to the ambient sound intensity and is generally used to detect the sound intensity of the surrounding environment. Using LM393 comparator output, the signal is clean, the waveform is good, and the driving ability is strong, more than 15MA. Fixed bolt hole is provided for easy installation and fixation. Blue digital potentiometer adjustable sensitivity.
Working voltage :3.3~5V DC
Output form: Digital switching output (high and low levels of 0 and 1)
Small board PCB size :3.2CM*1.7CM
