A3144 hall effect sensor arduino.

How to use hall effect sensor. If you remember the arduino waterflow sensor tutorial we implemented earlier the main component of the water flow sensor is the hall effect ic. Simply speaking a hall effect sensor or ic detects motion position or change in magnetic field strength of either a permanent magnet an electromagnet or any. This makes for a robust presence sensor.

The gnd of the sensor is connected to the gnd pin on the arduino. A3144 hall sensor the a3144e us1881 is an integrated hall effect latched sensor. A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high. Holding a magnet near the sensor will cause the output pin to toggle.

Thats nice but what does it do. A reed sensor also works nicely but can be. A hall effect sensor works on the principle of well hall effect. According to figure 3 hall effect sensor is powered up though arduino board and one led is also connected at the output of arduino board for checking the presence of magnetic field means this led would be turned on during the presence of magnetic field.

A3144 hall effect sensor 2 49 10 pcs 5v dc fan blower 8 95 5 pcs arduino uno 10 86. Neodymium magnets 5mm x 1mm 8 99 100 pcs. Figure 3 interfacing of a3144 hall effect sensor with arduino board. There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output.

The vout or signal pin of the hall effect sensor is connected to the arduino s interrupt pin digital pin 2. There are two main types of hall effect sensor one which gives an analog output and the other which gives a digital output. It is also mandatory to use a pull up resistor as shown below. Furthermore a 10k resistor is connected between the vcc and vout pins of the hall effect sensor.

En esta practica encendemos un led cuando ponemos el sensor en presencia de un campo magnético. A3144 is a digital output hall sensor meaning if it detects a magnet the output will go low else the output will remain high. This is done to pull the output of the hall effect sensor to 5v.
