This makes it useful for applications that need to monitor magnet position, movement, direction or relative magnetic-field intensity. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eWhen no magnetic field is present, the sensor output is normally positioned near half of the supply voltage. Bringing one magnetic pole closer causes the output voltage to increase, while reversing the pole causes the output voltage to decrease. The microcontroller can read this changing voltage through an analog-input pin.\u003c\/p\u003e\n\u003cp\u003eThe AH49E can detect magnetic fields produced by permanent magnets and electromagnets. It is commonly used in non-contact position sensing, joystick controls, speed detection, current-sensing experiments, motor control, magnetic encoders and educational electronics projects. \u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe module normally includes the AH49E sensor, supporting components and a simple pin interface for power, ground and analog signal output. Board design, pin order and supply range may differ between manufacturers, so the labels printed on the supplied module should always be checked before connection.\u003c\/p\u003e\n\u003ch3\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMagnetic-field detection\u003c\/li\u003e\n\u003cli\u003eMagnet polarity detection\u003c\/li\u003e\n\u003cli\u003eNon-contact position sensing\u003c\/li\u003e\n\u003cli\u003eLinear movement detection\u003c\/li\u003e\n\u003cli\u003eRotary-position sensing\u003c\/li\u003e\n\u003cli\u003eJoystick and control-lever projects\u003c\/li\u003e\n\u003cli\u003eMotor-position monitoring\u003c\/li\u003e\n\u003cli\u003eWheel and shaft detection\u003c\/li\u003e\n\u003cli\u003eMagnetic encoder projects\u003c\/li\u003e\n\u003cli\u003eCurrent-sensing experiments\u003c\/li\u003e\n\u003cli\u003eProximity sensing\u003c\/li\u003e\n\u003cli\u003eArduino analog sensor projects\u003c\/li\u003e\n\u003cli\u003eRobotics and automation systems\u003c\/li\u003e\n\u003cli\u003eScience and engineering projects\u003c\/li\u003e\n\u003cli\u003eDIY electronic circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePackage Contents:\u003c\/strong\u003e 1 × AH49E Linear Hall Effect Sensor Module\u003c\/p\u003e","brand":"MAJESTRONICZ","offers":[{"title":"Default Title","offer_id":48091021672606,"sku":null,"price":35.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0661\/9257\/2574\/files\/hall-sensor-ah49e.webp?v=1786017693","url":"https:\/\/majestronicz.in\/products\/ah49e-linear-hall-effect-sensor-module-analog-magnetic-field-detection-sensor-for-arduino-esp32-and-microcontrollers","provider":"MAJESTRONICZ","version":"1.0","type":"link"}
