{"product_id":"sensor-module-raindroop","title":"Hall Effect Sensor Module","description":"\u003cp\u003eHall Effect Sensor Module is used to detect the proximity of a magnet. It is very much smaller in size. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the onboard LED indicator.\u003c\/p\u003e\n\u003cp\u003eIt's fast (The turn-on threshold is 35-450 Gauss, the minimum hysteresis is 20 Gauss, and the operating voltage range is 4.5 - 24 volts. This module uses the Allegro MicroSystems A3144EUA sensor. It has a 3-pin interface, signal, V+, and GND.\u003c\/p\u003e\n\u003cp\u003eTo use this sensor\/switch, place a 10K pull-up resistor between the \"S\" pin and the middle pin (+), and connect the \"-\" pin to the ground. Supply voltage to the middle pin. The \"S\" pin will go low (gets pulled to the ground) and the onboard LED indicator will turn on when a magnet is brought near.\u003c\/p\u003e\n\u003ch5\u003e\u003cstrong\u003ePin Description :\u003c\/strong\u003e\u003c\/h5\u003e\n\u003cp\u003eVCC : 2.3 volts to 5.3 Volts\u003cbr\u003eGND : power supply ground\u003cbr\u003eAOUT (analog sensor output) : Arduino\/ MCU input\u003cbr\u003eDOUT (digital sensor output) : Arduino\/MCU input\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"STEMpitara","offers":[{"title":"Default Title","offer_id":43064470536288,"sku":"MCR-SEN-065","price":25.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0675\/2259\/2864\/files\/Pulse_95_1000x_81701011-5a6d-408a-ac79-e2fe1bb5a717.webp?v=1788863198","url":"https:\/\/stempitara.com\/ar\/products\/sensor-module-raindroop","provider":"Stempitara","version":"1.0","type":"link"}
