In this example we take a look at the KY-003 Hall Magnetic Sensor Module and connect this to a Raspberry Pi. The KY-003 consists of a 3144EUA-S sensitive Hall-effect switch These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended …
