The Hall effect sensor breakout with analog output is a versatile and reliable sensor module designed to detect and measure magnetic fields. It utilizes the Hall effect principle, where the presence of a magnetic field induces a voltage proportional to the strength and direction of the field.

This sensor module features an analog output, which provides a continuous voltage signal that varies in response to changes in the magnetic field. The analog output allows for precise and real-time monitoring of magnetic field strength. It is commonly used in applications such as position sensing, current sensing, and speed detection.

The module is typically powered with a supply voltage ranging from 2.25V to 5V, making it compatible with a wide range of systems.

The hall effect sensor (Hall Effect sensor) will be able to detect the magnetic field in its vicinity thanks to the aforementioned physical law. A magnetic field that can be created by a magnet, a current flowing through a conductor or some third source, the Hall effect sensor will recognize each. The stronger the magnetic field, the higher the voltage will be at the output of this sensor, so it is a sensor with analog output.

Dimensions: 22 mm x 22 mm
Logic voltage level: 0V – 5V
Operating voltage: 2.25V – 5V
Sensor: SI7211-B-00-IV

This small and simple module gives us a translation of logic level between two signals. In layman’s terms, if we take a signal with logical “unit” on 5V convert into a signal which logical “unit” has on 3.3V this module will help us. Something like this is useful in this case if we want to achieve communication between two devices from whom one works on 5V and the other on 3.3V, or any other combination of voltages. Directly connecting we would “burn” a device that works on 3.3V and a module gives us to avoid that.

This board is specialized for signal conversion for I2C communication protocol, and for this conversion it uses a special integrated circuit that enables communication at high speeds.

• Max. voltage: 30V
