Hall Effect Unit A3144E - Unit expansion module for development modules M5Stack

Hall sensor in the form of a Unit-type extension module for theM5Stackdevelopment module series. Equipped with threesensorsbased onA3144Echip, which are internally integrated and processed by74HCseries logical ICs. The module enablesmagnetic fielddetection, is used in alarm projects (e.g. door opening alarm), as a proximity sensor and for speed determination.

The kit includes a Hall sensor module, connection cable withGroveconnector and magnet.
