It delivers a linear sourcing output voltage determined by the supply voltage, and the output changes directly in proportion to the strength of the magnetic field.The integrated circuitry features low noise output, which makes it unnecessary to use external filtering.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eTypical Applications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMotor control\u003c\/li\u003e\n\u003cli\u003eMagnetic code reading\u003c\/li\u003e\n\u003cli\u003eFerrous metal detector\u003c\/li\u003e\n\u003cli\u003eCurrent sensing\u003c\/li\u003e\n\u003cli\u003ePosition sensing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Include:\u003c\/h2\u003e\n\u003cp\u003e1 x  LINEAR HALL EFFECT SENSOR 49E OH49E SS49E HALL ELEMENT\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eKEY FEATURES OF HALL-EFFECT SENSOR ANALOG 49E:\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSenses relative strength of magnetic field and provides analog voltage output\u003c\/li\u003e\n\u003cli\u003eCan differentiate between North and South pole of magnet\u003c\/li\u003e\n\u003cli\u003e3.3 and 5V compatible\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eHall-effect sensors are commonly used for measuring the speed of rotating assemblies where a magnet on the assembly alternately makes and breaks magnetic contact with the sensor as the assembly rotates.  They can also be used for applications such as determining when a door has been opened, position sensing and detecting the magnet\u003cspan style=\"font-size: 16px;\"\u003eic field created by current flow in a wire                \u003c\/span\u003e\u003cimg style=\"font-weight: inherit;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/49E-Hall-Effect-Sensor-Pinout.jpg?v=1789248732\" sizes=\"(max-width: 100px) 100vw, 100px\" alt=\"49E Hall Effect Sensor Pinout\" width=\"100\" height=\"330\" data-files=\"49E-Hall-Effect-Sensor-Pinout.jpg\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003cp\u003eThe 49E sensor can detect both the North and South pole of a magnet as well as the relative strength of the magnetic field.  The side of the sensor with the labeling is the side used for detection.\u003c\/p\u003e\n\u003cp\u003eHall-effect sensors have several advantages over mechanic switches, chief among them are that by being solid-state, there is no concern about contacts wearing out and the switching speed can be quite high.\u003c\/p\u003e\n\u003cp\u003eThe main challenge with using Hall-effect sensors usually resides around the mounting of the sensor and any associated magnets.\u003c\/p\u003e\n\u003ch3\u003ePower Supply\u003c\/h3\u003e\n\u003cp\u003eThe sensor can operate over a Vcc range of 2.3-10V.\u003c\/p\u003e\n\u003cp data-start=\"199\" data-end=\"376\"\u003eIf an MCU reads the output, you should operate the sensor at the same voltage as the MCU. This approach ensures the sensor output stays compatible with the analog input range.\u003c\/p\u003e\n\u003cp data-start=\"378\" data-end=\"605\"\u003eThe sensor typically draws 4mA, but the current varies with Vcc. For instance, at 3.3V it draws about 5mA, while at 5V it consumes around 7.8mA. Moreover, you can even power the device directly from an MCU digital output pin.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 1.5em; font-weight: bold;\"\u003eAnalog Output\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"232\" data-end=\"547\"\u003eThe sensor outputs an analog voltage. When it detects no magnetic field, the output rests at approximately half of Vcc. If you bring the south pole of a magnet close, the output ramps linearly upward toward Vcc. On the other hand, if you move the north pole near, the output ramps linearly downward toward ground.\u003c\/p\u003e\n\u003cp data-start=\"549\" data-end=\"832\"\u003eFor example, when Vcc is 5V and no magnetic field is present, the output stays around 2.5V. As soon as the south pole comes closer, the output rises linearly to a maximum of about 4.2V. Conversely, if the north pole approaches, the output drops linearly to a minimum of about 1.0V.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eOUR EVALUATION RESULTS:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cp\u003eHall-effect sensors are quite useful in a number of applications and one of the more under utilized electronic components available to hobbyists.  These particular sensors are used in many of the analog hall effect sensor modules that come out of China.\u003c\/p\u003e\n\u003cp\u003eThe program below monitors the output of the sensor and reports the value of the analog output.  Simply hook the sensor up to 5V \/ 3.3V and ground and connect the sensor output pin to a analog pin on the MCU.  We use pin A0 in this example but this can be any analog input pin.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Electronics Hub","offers":[{"title":"Default Title","offer_id":54467545661753,"sku":"product-16943","price":0.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/OIP-8-4.jpg?v=1789248740","url":"https:\/\/electronicshub.pk\/products\/linear-hall-effect-sensor-49e-electronics-hub","provider":"Electronics Hub","version":"1.0","type":"link"}
