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"},{"product_id":"gravity-i2c-non-contact-ir-temperature-sensor-for-arduino-mlx90614-dcc","title":"Gravity: I2C Non-contact IR Temperature Sensor for Arduino (MLX90614-DCC)","description":"\u003cdiv class=\"desc\"\u003e\n\u003cdiv class=\"desCon\"\u003eWe can divide temperature measurement in to two types: contact and non-contact. Contact measurement can only accurately measure temperature when the testing object and the sensor reach thermal equilibrium. This can mean longer response times and reading inaccuracies offset by ambient temperature. By contrast, non-contact measurement uses infra-red radiation to measure the temperature and does not require a direct touch. Additionally, this method of measurement can be read quickly and accurately.\u003cbr\u003e\u003cbr\u003eIn recent years non-contact measurement methods have been used for medical, environmental monitoring, home automation, automotive electronic, aerospace, and military applications.\u003cbr\u003e\u003cbr\u003eOur latest infrared temperature measurement module is the MLX90614. This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing, and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted in to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted in to a temperature value. The MLX90614 is self-calibrating and has a low noise amplifier integrated in to the signal processing chip. The chip itself is a 17 bit ADC and DSP device, giving accurate and reliable results.\u003c\/div\u003e\n\u003ch2 class=\"desCon\"\u003eConnection Example - DFRduino UNO\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0176\/3274\/files\/I2C_Non-contact_IR_Temperature_Sensor_features_1.jpg?v=1692887678\u0026amp;width=700\"\u003e\u003c\/p\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eModel: MLX90614-DCC\u003c\/li\u003e\n\u003cli\u003eMeasurement Accuracy: ±0.2°C (body temperature range)\/ ±0.5℃\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 3.3V - 5V\u003c\/li\u003e\n\u003cli\u003eTemperature: -70.01°C to +380°C, (0.01°C resolution)\u003c\/li\u003e\n\u003cli\u003eInterface Type: I2C\u003c\/li\u003e\n\u003cli\u003eInterface Line Sequence: VCC, GND, SCL, SDA\u003c\/li\u003e\n\u003cli\u003eFOV: 35°\u003c\/li\u003e\n\u003cli\u003eDimensions: 31.5 x 18 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 15g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Wiki\u003c\/li\u003e\n\u003cli\u003eDIY Temperature Gun Using Arduino and MLX90614 Module\u003c\/li\u003e\n\u003cli\u003eMore Documents \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cdiv class=\"desCon\"\u003e\n\u003cul\u003e\n\u003cli\u003e1x On-contact IR Thermometer Sensor\u003c\/li\u003e\n\u003cli\u003e1x JST PH2.0 4-Pin cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":43493266849869,"sku":"phd1787258304613","price":11.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/gravity-i2c-non-contact-ir-temperature-sensor-for-arduino-mlx90614-dcc_1.jpg?v=1787258308"}],"url":"https:\/\/www.grandorchard.shop\/collections\/sensor.oembed","provider":"My Store","version":"1.0","type":"link"}
