Magnetic Imaging Tile - 8x8
·
Visualise magnetic fields in real time with a dense 8x8 array of Hall-effect sensors. This tile lets you observe nearby magnets, current flow in wires and fields generated by electric motors as a live magnetic image.The sensors are highly sensitive, with best imaging performance within 1cm to 2cm...
Gravity: Analog 50A Current Sensor (AC/DC)
INTRODUCTION This is a breakout board for the fully integrated Hall Effect based linear ACS758 current sensor. The sensor gives precise current measurement for both AC and DC signals.The thickness of the copper conductor allows survival of the device at high overcurrent conditions. T...
Gravity: 360 Degree Hall Angle Sensor
The Hall Angle Sensor is a miniature 360 degree sensor which works based on the principle of the Hall effect. It is compatible with the DFRobot Gravity sensor interface, and works with a 5V DC power supply. The analog output is also 0~5V so it can work directly with Arduino. The Hall an...
Gravity: Analog 20A Current Sensor
The Gravity Analog 20A Current Sensor measures both AC and DC current using the Hall effect, outputting a proportional analog voltage to your microcontroller. With high-voltage isolation built into the circuit design and a non-conductive acrylic base plate, it's designed for safe use in automatio...
Hobby Motor with Encoder - Plastic Gear (Pair, Red)
·
These DG01D-E hobby motors come as a matched pair, each with a built-in hall effect speed encoder and a 1:48 plastic gearbox. The hall sensor detects the magnetic plate's polarity — south pole outputs high, north pole outputs low — giving you precise speed and position feedback for closed-loop mo...
Hall-Effect Sensor - AH1815 (Non-Latching)
The AH1815 is an integrated Hall-Effect non-latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A...
Hobby Motor with Encoder - Plastic Gear (Red)
·
Add motion and feedback to small robotics builds with this single DC gearmotor and integrated Hall effect speed encoder. Instead of simply driving a motor open-loop, your microcontroller can count encoder pulses to track wheel rotation and speed for more accurate navigation and speed control.The ...
