Accurate Acoustic Sensor – Sound Frequency to Voltage Converter
The project presented here is a sensitive sound sensor. The circuit converts sound frequency and outputs DC voltage. The board consists of LM358 OPAMP and LM2907 IC. LM358 is used as a dual-stage microphone preamplifier and LM2907 acts as a frequency to voltage converter. The circuit...
