Specification.
LM393 sound digital Sensor 3.3-5VDC
- Single-channel signal output.
- The output effective signal is low level.
- When there is sound, outputs a low level and the signal light.
- Can be used to control light, give sound and light alarm working with a Photosensitive sensor, and sound control, sound detect.
- Circuit board output switch quantity.
- Size : 32mm x 17mm x 15mm (length x width x height).
- Main chip: LM393, Electret condenser microphone.
- Working voltage: DC 3.3-6V.
- Low quiescent current drain: 4mA
This LM393 sound digital Sensor 3.3-5VDC is a simple microphone. Based on the power amplifier LM386 and the electret microphone, it can be used to detect the sound strength of the environment. The value of output can be adjusted by the potentiometer. In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analogue input terminals and one binary digital output.
