It uses an instrument circuit and a low-noise microphone, which enable it to accurately measure the sound level of the surrounding environment. It can be applied to environmental noise testing, such as highway noise monitoring stations, bedroom noise monitoring, etc. Nowadays, there are many kinds of sounds surrounding, some of which are really noisy. It is really essential to measure whether the sound is noisy enough to do damage to our health.\u003c\/p\u003e\n\u003cp\u003eSound level meter (also known as the decibel meter, noise meter) is a basic noise measurement instrument. We have launched a sound level meter that is compatible with Arduino, plug-and-play. It can accurately measure the sound level of the surrounding environment. This product uses instrument circuit and a low-noise microphone, which make it highly precise. It supports 3.3~5.0V wide input voltage, 0.6~2.6V voltage output. The decibel value is linear with the output voltage, which leads to a simple conversion without complex algorithms. The connector is plug-and-play, without welding, so this product can be easily used in your application.\u003c\/p\u003e\n\u003cp\u003eSound level meter is widely used in environmental noise detection, such as highway noise monitoring stations, room noise monitoring, and so on. It’s time for you to DIY a sound level detector to protect your hearing.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e Attention:\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe black film on the microphone is a sensitive component; do not touch it with fingernails or other sharp objects.\u003c\/p\u003e\n\u003cp\u003eDo not place this module on the surface of the conductor or the semiconductor; otherwise, it will short the microphone’s pins. It is recommended to place this module on a dry insulator’s surface or fix with nylon columns to hang in the air.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHigh Precision: use instrument circuit, low noise microphone\u003c\/li\u003e\n\u003cli\u003eWide Voltage Input: 3.3~5.0V\u003c\/li\u003e\n\u003cli\u003eSimple Conversion: linear analog output, 0.6~2.6V linear correspondence, 30~130dBA; no complex algorithm is required\u003c\/li\u003e\n\u003cli\u003eEasy to Use: plug and play, without soldering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMeasuring Range: 30dBA ~ 130dBA\u003c\/li\u003e\n\u003cli\u003eMeasurement Error: ±1.5dB\u003c\/li\u003e\n\u003cli\u003eFrequency Weighted: A Weighted\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 31.5Hz ~ 8.5KHz\u003c\/li\u003e\n\u003cli\u003eTime Characteristics: 125ms\u003c\/li\u003e\n\u003cli\u003eInput Voltage: 3.3 ~ 5.0V\u003c\/li\u003e\n\u003cli\u003eInput Current: 22mA@3.3V, 14mA@5.0V\u003c\/li\u003e\n\u003cli\u003eOutput Voltage: 0.6 ~ 2.6V\u003c\/li\u003e\n\u003cli\u003eModule Size: 60mm * 43mm \/ 2.37in*1.68in\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eShipping List\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eAnalog Sound Level Meter x1\u003c\/li\u003e\n\u003cli\u003eGravity Analog Cable 3Pin x1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/wiki.dfrobot.com\/sen0232\/\" target=\"_blank\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/github.com\/Robert-MARKII\/Document\/raw\/master\/SEN0232_Layout.pdf\" target=\"_blank\"\u003eLayout\u003c\/a\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cfooter\u003e\u003c\/footer\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":67625759703117,"sku":"E32002-001","price":87.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E32002-win1.jpg?v=1791492984","url":"https:\/\/www.mlab.com.au\/products\/gravity-analog-sound-level-meter","provider":"MLAB","version":"1.0","type":"link"}
