{"product_id":"piezoelectric-ribbon-sensor-2-feet-600mm-long","title":"Piezoelectric Ribbon Sensor - 2 feet \/ 600mm long","description":"\u003cp\u003eThis thin silvery ribbon is an interesting sensor. It's made of 2mm wide by 600mm long piezoelectric film sandwich. Piezo film can be used to detect motion or vibration - when shifted around or touched, it creates a small current pulse across the terminals. If a 1 Mega-ohm resistor is placed across the two terminals you will see the current converted into a voltage that can be read by an analog-to-digital converter (ADC).\u003c\/p\u003e\n\u003cp\u003eBasically, connect one tab to ground, another tab to the ADC input of your microcontroller or ADC, and a 1M resistor across both, then read the analog input while touching\/poking\/twisting the piezo element and you'll see little spikes of voltage whenever the piezo has vibrated. This Arduino guide shows a wiring and code example.\u003c\/p\u003e\n\u003cp\u003eUsually, piezos are round hard disks, which is why we thought this thin and flexible version was interesting. There could be some unique sensing projects that need to sense over a long, flexible distance. Like perhaps a wearable project with a sensor sewn into clothing, or feedback for a robotic actuator. Initially, these were designed for sleep sensors, to be placed underneath a mattress to detect how much the sleeper shifted around through the night.\u003c\/p\u003e\n\u003cp\u003eComes with a dual metal contact tab with 0.2\" spacing between the two contacts, on one end. You can cut this down if desired but once cut you won't be able to reattach!\u003c\/p\u003e\n\u003ch2\u003eTechnical Details\u003c\/h2\u003e\n\u003cdiv class=\"panel-collapse collapse in\" id=\"tab-technical-details-content\"\u003e\n\u003cul id=\"product-files\"\u003e\n\u003cli\u003eLength: 2 feet \/ 600mm long\u003c\/li\u003e\n\u003cli\u003eWidth: 8mm\u003c\/li\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43493266686029,"sku":"izg1787258302669","price":15.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/piezoelectric-ribbon-sensor---2-feet-600mm-long_1.jpg?v=1787258307","url":"https:\/\/www.grandorchard.shop\/products\/piezoelectric-ribbon-sensor-2-feet-600mm-long","provider":"My Store","version":"1.0","type":"link"}
