The 49E sensor operates on a supply voltage of 3V to 6.5V, making it fully compatible with both 3.3V and 5V microcontroller platforms including Arduino, ESP32, Raspberry Pi, and similar boards. Simply connect VCC, GND, and read the analog output pin.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between 49E, OH49E, and SS49E Hall sensors?\u003c\/h4\u003e\n\u003cp\u003eA: The 49E, OH49E, and SS49E are functionally equivalent linear Hall effect sensors from different manufacturers (Allegro, Honeywell, and others) that share the same pin configuration and performance characteristics.
