SENS-LM2904 Analog Decibel Detection LM2904 Sound Intensity Detection Module.
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 being more convenient and solving the pain of waveform acquisition. It can also be directly used as a decibel sensor; this module has high sensitivity. It basically has no problem in detecting human voice within 10 meters in a closed environment. Integrated signal and power indicator light facilitate users' intuitive signal acquisition.
