{"product_id":"hall-effect-unit-a3144e-hall-sensor","title":"Hall Effect Unit (A3144E Hall Sensor)","description":"\u003cp\u003eThis hall effect unit has three A3144E hall sensor switches, improved by 74HC series gate integrated circuits for reliable signal processing. This unit provides a low-level signal when the south pole of a magnet is near the front of the sensor or the north pole is close to the back, lighting up the internal LED indicator for visual feedback.\u003c\/p\u003e\n\u003cp\u003eIt is ideal for various uses, including door sensor alarms, proximity detection, and rotation speed measurement. With the front side designed to detect the north pole and output a low level when sensing the south pole of a magnetic field, it provides easy magnetic sensing for a range of projects.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUnipolar Hall switch sensor\u003c\/li\u003e\n\u003cli\u003eFast response and high sensitivity\u003c\/li\u003e\n\u003cli\u003eStatus indicator\u003c\/li\u003e\n\u003cli\u003eLow-level output\u003c\/li\u003e\n\u003cli\u003eLego compatible\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable width=\"371\" style=\"height: 152px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eHall Sensor\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e3x A3144E\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eLogic IC\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e74HC08D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eStatus Indication\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003eRed LED\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eOutput Level\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003eActive Low\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eNet weight\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e4g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eGross Weight\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e17g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003eProduct Size\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e24 x 32 x 8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 192.869px; height: 19px;\"\u003ePackage Size\u003c\/td\u003e\n\u003ctd style=\"width: 168.693px; height: 19px;\"\u003e67 x 52 x 11mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/docs.m5stack.com\/en\/unit\/hall\" title=\"Hall Effect Unit Wiki\"\u003eProduct Wiki\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x Hall Effect Unit\u003c\/li\u003e\n\u003cli\u003e1x GROVE Cable (20cm)\u003c\/li\u003e\n\u003cli\u003e1x Magnet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M5Stack","offers":[{"title":"Default Title","offer_id":50847143788817,"sku":"U084","price":5.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0901\/6285\/6209\/files\/hall-effect-unit-a3144e-hall-sensor-m5stack-u084-72074725884289.jpg?v=1735207590","url":"https:\/\/abcd3032.myshopify.com\/zh\/products\/hall-effect-unit-a3144e-hall-sensor","provider":"Tayyab Zak","version":"1.0","type":"link"}
