{"title":"Large Enclosed Piezo Element w/Wires","handle":"large-enclosed-piezo-element-w-wires","url":"/products/large-enclosed-piezo-element-w-wires","description":"This large enclosed piezo element (30 mm diameter) converts vibration to voltage and voltage to vibration, making it useful both as a buzzer for generating tones and as a sensor for detecting knocks and impacts. The enclosed housing includes mounting holes for easy attachment to panels, enclosures, or drum pads.\n\nRated for up to 12 Vpp, it also works well with 3.3 V or 5 V square waves and is plenty loud for alert and notification applications. Pre-attached wires are suitable for breadboard use, though they may be too thin for direct insertion into Arduino socket headers.\n\nKey Features\n\n\nDual Purpose – Use as a buzzer (output) or knock/vibration sensor (input)\n\nEnclosed Housing – Protective case with mounting holes\n\n30 mm Diameter – Large element for strong output and sensitive detection\n\nPre-Wired – Thin leads attached, ready for breadboard connection\n\nWide Voltage Range – Rated up to 12 Vpp, works with 3.3 V and 5 V logic\n\n\nIdeal For\n\nBuzzers, alarms, and alert tones\nKnock and tap detection sensors\nDIY drum pads and musical instruments\nArduino and microcontroller projects\n\n\nResources\n\n\nArduino Tone Tutorial – Generating tones with a piezo\n\nArduino Knock Tutorial – Using a piezo as a knock sensor\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":8975,"title":"Default Title","sku":"AF-1739","price":2.06,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":105,"option1":"Default Title"}]}
