KY-024 Hall effect sensor

Operating Voltage:

• 3.3V to 5V DC (typically powered by microcontrollers like Arduino)

Output Type:

• Analog Output: Provides a voltage proportional to the magnetic field strength (typically 0V to VCC).
• Digital Output: Provides a HIGH or LOW signal depending on the magnetic field detection.

Detection Type:

• Hall Effect: Senses the presence and strength of magnetic fields (detects both north and south poles of magnets).

Sensitivity:

• Varies depending on the sensor and magnetic field strength but is typically designed for detection at 5-10 cm distance from the magnet.

Magnetic Field Detection:

• The sensor is triggered when the magnetic field strength exceeds a certain threshold, which can be adjusted via a potentiometer on the module.

Output Voltage Range (Analog):

• Typically ranges from 0V to VCC (depending on the magnetic field strength).

Digital Output Threshold:

• The digital output is triggered (high) or deactivated (low) when the magnetic field crosses a predefined threshold.

Operating Temperature Range:

• Typically -40°C to +85°C (depends on the specific model).
