Unlike a basic digital magnetic switch, this \u003cstrong\u003elinear Hall effect sensor\u003c\/strong\u003e measures relative field strength for smoother feedback in robotics, automation, motor projects, and prototyping. It pairs well with Arduino, ESP32, and other microcontrollers with ADC inputs for magnet tracking, custom controls, and DIY sensing systems easily.\u003c\/p\u003e","brand":"ShillehTek","offers":[{"title":"Default Title","offer_id":52637502570783,"sku":"NB057","price":2.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4340\/8415\/files\/49e-linear-hall-effect-sensor-front-back-01.png?v=1783990386","url":"https:\/\/shillehtek.com\/products\/linear-hall-effect-sensor-49e-arduino-esp32","provider":"ShillehTek","version":"1.0","type":"link"}
