They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it?

My goal is to make a device that can be used to sense some metal approaching it. If this is not your local representative, find your local sales rep here.

A and A Datasheet. Units — — 4. High precision in output levels is obtained by w1301 gain and offset trim adjustments made at end-of-line during the manufacturing process. Samples are no longer available. This proportionality is specified as alllegro magnetic sensitivity of the device and is defined as: These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.

I assumed that the differences were determined by me approaching and retracting the Neodymium magnet from the sensor.

Do I have to process the raw a3101 in order to get some better results? Allegro are generally pretty good at application notes, so I would start there, before even starting with code.

Sale of this device is currently restricted to existing customer applications. Is there another way zllegro wire the sensor? The A and A feature a ratiometric output.

Please contact the Allegro Marketing department for additional information. For the latest version of this document, visit our website: Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.

Thank you and have a nice week ahead! Thereafter I wrote a sketch which checks whether there are voltage fluctuations in the sensor using the digitalread function and then printing the results in the console when I approach a Neodymium magnet towards it.

Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. Read the data sheet.

Just a quick look at the spec suggests that the output is analogue, so digital read may not be much good – I would expect this device alllegro give a voltage output on the output pin, so analogue read would be more appropriate. A3101 results show me random numbers varying from to which repeat at regular intervals.

Therefore I would like to ask the kind forum members the following questions: Two output sensitivity options are provided: One of my friends recommended me to buy an Allegro A sensor.

Are the results voltages or random numbers? Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.

Two device package types are available: This classification indicates that the product is obsolete and notice has been given. Because I get the same results when I “read” both an empty slot and the slot with the sensor, is it a130 that my sensor is broken? Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.

Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

The Allegro site suggests that this is an end of life device, so maybe not the best choice. However, Allegro MicroSystems, Inc. Note that some of these devices need a load resistor on the output pin plus decoupling Vcc to GND They are pretty resistant to abuse getting it wired up incorrectlybut will only take so much.

Linearity in percent is measured and defined as:
