This makes for a robust presence sensor.
Sensor efecto hall a3144.
It is also mandatory to use a pull up resistor as shown below to keep the output high when no magnet is detected.
5v dc voltages are used for power on this sensor.
The a3144 is an integrated hall effect non latching sensor.
A3144 is a small size having superior temperature stability and gives a very fast response.
Sensitive hall effect switches for high temperature operation a3144 datasheet a3144 circuit a3144 data sheet.
From these pins first pin is power pin and is used for power on this sensor.
Pin configuration of a3144 hall effect sensor.
The a3144 is an integrated hall effect non latching sensor.
We need to use a pull up resistor with the output for proper functioning.
Second one is the ground pin and is used for supplying ground to this sensor.
El a3144 es un sensor de efecto hall con retencion de estado.
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.
Every a 3144 hall effect consist of three pins which are shown in figure 2.
En esta practica encendemos un led cuando ponemos el sensor en presencia de un campo magnético.

This sensor gives the digital output as high if it detects the magnetic field else the output is low.
This makes for a robust presence sensor.
A reed sensor also works nicely but can be limited by the glass encapsulation and size.
A3144 lt sensitive hall effect switches for high temperature operation.
Holding a magnet near the sensor will cause the output pin to toggle.
