When the ambient ambient sound intensity exceeds the set threshold, the module OUT outputs a low level.\u003cbr\u003e· The small board digital output OUT can be directly connected to the single-chip microcomputer, and the high-low level is detected by the single-chip microcomputer, thereby detecting the sound of the environment.\u003cbr\u003e· The small board digital output OUT can directly drive the relay module, which can form a voice-activated switch.\u003cbr\u003e· It can detect the sound intensity of the surrounding environment. Note: This sensor can only identify the presence or absence of sound (according to the principle of vibration). It cannot identify the volume of the sound or the sound of a specific frequency.\u003c\/div\u003e\n\u003cdiv class=\"FullDescription\"\u003e\n\u003c!-- show up to 2 reviews by default --\u003e\n\u003cp\u003e\u003cbr\u003e\u003cb\u003eSpecification：\u003c\/b\u003e\u003cbr\u003e Working voltage：3.3V-5V\u003cbr\u003e Small board PCB size: 3.2cm x 1.7cm\u003cbr\u003e\u003cbr\u003e Adjustable sensitivity (adjusted by blue digital potentiometer）\u003cbr\u003e With fixing bolt holes for easy installation\u003cbr\u003e VCC connect to 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)\u003cbr\u003e GND connect to GND\u003cbr\u003e OUT connect to switch output interface (0 and 1)\u003cbr\u003e \u003cbr\u003e\u003cb\u003ePackage included：\u003c\/b\u003e\u003cbr\u003e 5 x Sound Microphone Sensor Detection Module\u003cbr\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Treedix Official","offers":[{"title":"Default Title","offer_id":42602631921918,"sku":"TRX2-0031","price":7.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0632\/8483\/8654\/products\/519F07ta86L.jpg?v=1648431255","url":"https:\/\/treedix.com\/it\/products\/treedix-5pcs-sound-microphone-sensor-detection-module-compatible-with-arduino-avr-pic","provider":"Treedix Official","version":"1.0","type":"link"}
