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

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 compatible Package Included: - 1x Hall Effect Unit - 1x GROVE Cable(20cm) - 1x Magnet Application: - Door sensor alarm - Magnetic field proximity sensing - Speed measurement Specification: Specification Parameter Hall sensor A3144E * 3 Logic IC 74HC08D Status indication RED LED Output Level Active Low Net weight 4g Gross weight 17g Product Size 24*32*8mm Package Size 67*52*11mm EasyLoader: Click to download EasyLoader is a concise and fast program writer, which has a built-in program related to the product.
