DFRobot Gravity - Linear/Analog Hall Effect Sensor with Magnetic Field Range - DFR1132
DFRobot Gravity module with Hall sensor designed to measure and monitor the intensity of the magnetic field . It is equipped with 3 analog pins and an LED indicator that signals the detected magnetic field. It is powered by a voltage from 3.3 V to 5 V, its supply current is from 4.2 mA to 8 mA. It is characterized by a low level of noise, which allows only minimal interference. It integrates with controllers such as Arduino, Micro:bit, UNIHAKER , thanks to which it will work, for example, in detecting position and speed in robotics or security systems.

DFRobot Gravity module with Hall sensor.
Key Features of the DFRobot Gravity DFR1132 Sensor
- Bipolar sensor : detects magnetic fields at a distance of < 1 cm (depending on the intensity and direction of the magnetic field)
- Low noise : the integrated circuit has a low noise level, making the measurements stable and precise
- Single output current source : the output signal is stable and not susceptible to voltage fluctuations
- Built-in LED : lights up when a magnetic field is detected, the user can quickly control the device's operation
- Wide compatibility: easy connection with microcontrollers such as Arduino , Micro:bit and UNIHIKER , enabling a variety of applications
- Easy to use : allows for quick and easy installation, making the sensor user-friendly for beginners
Connecting the Hall sensor
The sensor works with a microcontroller equipped with analog inputs ( Arduino , Micro:bit, UNIHIKER). To start work, connect:
- VCC to 3.3V or 5V power source (as required by the sensor)
- GND to system ground
- A to the analog pin of the microcontroller
Once connected, the sensor will generate an analog signal proportional to the strength of the detected magnetic field, which allows for accurate monitoring of field changes and processing of results in electronic designs.
Compatible with Arduino, Micro:bit and UNIHAKER.
Gravity sensor operation
The advanced DFRobot Gravity DFR1132 board has core circuits that convert magnetic induction force directly into output voltage. High accuracy allows the sensor to be used in many solutions that require precise magnetic field detection . These can be projects related to industrial control, scientific research, security systems and various projects with electronic devices. The sensor responds to magnetic fields when:
- the south pole of the magnet approaches the sensing surface, then the magnetic field becomes stronger and the output voltage increases above the midpoint and gradually increases
- As the north pole approaches the sensing surface, the output voltage drops below the midpoint and gradually decreases.
