Product Description

Details

This module usually used for detecting the sound intensity. When sound intensity can not reach the value, DO output is high level. When light intensity over than the value, the module DO output is low level. The module digital output DO can be directly connected with the microcontroller,use microcontroller detect high or low level, so that can detect the sound. Can use this board digital output DO port drive relay module directly(our store on sale these relay modules), can use as a voice switch. Detect sound intensity. Attention, this module only can recognize weather have sound, does not recognize the sound level or specific frequency of sound. Accuracy adjustable Operating voltage 3.3V-5V Output model: digital switch outputs (0 and 1,high or low level) With a mounting screw hole PCB size: 3.4cm * 1.6cm Interface Description (3-wire) A. VCC -- 3.3V-5V voltage)(can connect directly with 5V microcontroller or 3.3V microcontroller) B. GND -- GND C. DO  -- board digital output interface (0 and 1) D. Empty
