Hall Sensor Module 49E 3144 High Sensitivity Induction Switch North South Pole Detection for DIY Electronic Projects Compatible

Highlights: About the Module: This linear Hall sensor module measures magnetic induction, translating it into a proportional voltage output. The default output voltage under zero field (B=0GS) is half the supplied voltage. Example: If a +5.0V input is used (with an on-module 3.3V LDO for the MCU and sensor), when no magnet is present, the A0C output voltage equals 3.3V divided by 2, resulting in 1.65V. Bringing an S-pole near the module raises the output voltage in a linear manner, causing the blue LED to illuminate. Introducing an N-pole decreases output voltage with increased field, lighting the red LED. Built-in circuit reduces noise, so less external filtering is required. Precision resistors keep performance stable and accurate even with temperature changes. Uses: 1. N/S polarity detection 2. Magnetism detection: output 1.6mV per GS (AOC pin) Technical Info: Color: Refer to image Included: 1 Pc Notes: 1. Allow 2%–5% measurement variance. 2. Actual color can vary from photo due to light or screen differences.
