HS5897 Analog Decibel Detection Lm2904 Sound Intensity Detection Module
Product introduction
Using the original professional LM2904 signal control chip, the detection effect is stable. Analog signal output can detect the sound size, whistle, sound intensity and other linear analog signal in AD acquisition time is more convenient, solve the pain of waveform acquisition, can also be directly used as a decibel sensor, this module has high sensitivity. It is basically no problem to detect human voice within 10 meters in a closed environment. Integrated signal and power indicator light facilitate users' intuitive signal acquisition.
