ALLNET 4duino Potentiometer and Analog Hall Sensor Module (4duino_B19)

The ALLNET 4duino Potentiometer and Analog Hall Sensor Module (4duino_B19) is a versatile dual-sensor module designed for Arduino, Raspberry Pi, and other microcontroller platforms. It combines a rotary potentiometer and a linear analog Hall effect sensor on a compact 32 x 14 mm PCB, providing two independent analog voltage outputs for precise control and magnetic field detection.

Advantages

This module offers a cost-effective and space-saving solution for projects requiring both manual input (via potentiometer) and contactless magnetic sensing. The analog outputs are easy to read with any microcontroller's ADC, enabling smooth variable control and accurate magnetic field measurement. Its standard 2.54mm header pins ensure simple integration with breadboards and prototyping boards.

Suitable for

• DIY electronics and hobbyist projects
• Robotics for position sensing and motor control
• Prototyping and educational environments
• Magnetic field detection and proximity sensing

Key specifications

• Sensor Types: Rotary Potentiometer and Linear Analog Hall Effect Sensor
• Output Signal: Analog Voltage (0V to VCC)
• Operating Voltage: 3.3V - 5V DC
• Interface: 3-pin header per sensor (VCC, GND, Signal)
• Number of Sensors: 2
• Module Dimensions (L x W): 32 x 14 mm
• Connectivity: Standard 2.54mm header pins

Recommendations

For best results, power the module with a stable 5V supply and connect the analog outputs to ADC pins on your microcontroller. The Hall sensor output is proportional to the magnetic field strength; use a magnet with known polarity for consistent readings. This module is ideal for educational kits and prototyping labs.
