The Magnetic Hall Effect Sensor Board is a sensor board that provides digital output when brought close to an object with a magnetic field, such as a magnet.
You can adjust the sensitivity of the sensor board using the trimpot on the board, and it can be easily used in many projects, including Arduino. Normally, the sensor board outputs 0V from the digital output pin, but when a magnet is brought close, it will start outputting 5V.
You can order the Magnetic Hall Effect Sensor from SAMM Market in the Magnetic Sensors category at an affordable price, with same-day shipping and fast delivery options.
