Sound Sensors
Each sound sensor is in a plastic enclosure containing a miniature electret microphone, amplifier circuitry, a replaceable 9 V battery, and a 10 mm white LED. Responsive to sound pressures levels from 80 to 104 dB SPL, each sound sensor has a magnetic panel built into its base that holds it to the magnetic base and completes the circuit. When testing is complete, simply remove the sound sensor from the magnetic base, and power is removed.
