M5Stack® Hall Effect Sensor Module A3144E Logic IC 74HC08D ESP32 Development Board Door Sensor Alarm

Description Hall effect Unit Three A3144E Hall sensor switches are integrated internally which are processed by 74HC series gate integrated circuits Low level signal can be generated when the magnet S pole is close to the top of the sensor or the N pole is close to the back and the internal LED indicator will light up It is widely used in applications such as door sensor alarms proximity sensors rotation speed measurement and so on The front side is the North pole and the low level is output when the south pole signal of the magnetic field is sensed Futures Unipolar Hall switch sensor Quickly response and high sensitivity Status indicator Low level output Leigo compatiblePackage Included 1x Hall Effect Unit 1x GROVE Cable 20cm 1x MagnetApplication Door sensor alarm Magnetic field proximity sensing Speed measurementSpecification SpecificationParameterHall sensorA3144E 3Logic IC74HC08DStatus indicationRED LEDOutput LevelActive LowNet weight4gGross weight17gProduct Size24 32 8mmPackage Size67 52 11mmEasyLoader Click to downloadEasyLoader is a concise and fast program writer which has a built in program related to the product It can be burned to the main control by simple steps to perform a series of function verification Please install the corresponding driver according to the device type M5Core host Please click here to view the CP210X driver installation tutorial M5StickC V T ATOM series can be used without driver PinMap M5Core PORT B GPIO26GPI
