1. Sound Microphone Sensor XD-74 Detection Module for AVR PIC

   Great Sensors for Project. Having Fun With Electronics and Programming! Description:This module can detect ambient sound intensity.NOTE: This sensor can only recognize the presence or absence of sound, can not recognize the lever of sound or the sound of a specific frequency.Sensitivity adjustable.output form: Digital switch output (1 s and 0 s + v)When the ambient sound intensity does not reach the set threshold, the module outputs a high level. When the ambient sound intensity exceeds the set threshold, the module outputs a low level.Digital Output "OUT" can be directly connected with MCU. Specification:Working Voltage: DC 3.3V-5VPCB Size: 31.5mm x 17mm (L*W)Fixed Hole Diameter: 3mm Package Includes:1 x Sound Detection Sensor Module .
