Two output sensitivity options are provided: Note alllegro 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.

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

My goal is to make a device that can be used to sense some metal approaching it. Hello I think you need to go back to the basics Have you looked at the data sheet for this device? High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.

The on-chip output stage is designed to provide linear output at a supply voltage of 5 V. Integrating the Hall sensing element and the allegro on a single chip minimizes many of the problems normally associated with low voltage level analog signals.

They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. Just a quick look at the spec aolegro that the output is analogue, so digital read may not be much good – I would expect this device to give a voltage output on the output pin, so analogue read would be more appropriate. The Allegro site suggests that this is an end of allegri device, so maybe lalegro the best choice.

Please contact the Allegro Marketing department for additional information. Are the results voltages or random numbers? Samples are no longer available.

If yes, how can I test to find it out? Two device package types are available: Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.

Allegro MicroSystems – A and A Continuous-Time Ratiometric Linear Hall Effect Sensor ICs

One of my friends recommended me to buy an Allegro A sensor. If this is alletro your local representative, find your local sales rep here.

I think your best bet is to decide what you really want to achieve – metal or magnet, choose a different device like the recommended A replacement.

Therefore I would like to ask the kind forum members the following questions: Thank you and have a nice week ahead! Good day everyone, I am a new face in the world of Arduino and electronics and I wanted to try my luck with an Allegro A magnetic alletro.

They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.

In the quiescent state no significant 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. Sale of this device is currently restricted to existing customer applications.

Linearity in percent is measured and defined as: Because I get the same results when I “read” both an empty slot and the slot with the sensor, is it possible that my sensor is broken? In reality, after modifying the sketch and adding an extra variable to read an unused slot, I realized that the results were similar in nature. These features make the A and A ideal for use in position sensing systems, for both linear target alleyro and rotational target motion.

The A and A feature a ratiometric output. Thereafter I wrote a sketch which checks whether there are voltage fluctuations in the sensor using the digitalread alleyro and then printing the results in the console when I approach a Neodymium magnet towards it.

However, Allegro MicroSystems, Inc. Although the application of very high magnetic fields does not damage these devices, it does force their output into a nonlinear region. The device should not be purchased for new design applications because of obsolescence in the near future.

Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. We’ll notify you when there are updates to this product.

Before placing an order, the user is cautioned to verify that the information being relied upon is current. Two output sensitivity options are provided: Does a magnetic sensor allwgro fluctuations caused by approaching a metal piece to it? This proportionality is specified as the magnetic sensitivity of the device and is defined as: August 30, Recommended Substitutions: Supply Voltage Device Symmetry vs.

These features make the 1a301 and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field.

A and A Datasheet. This classification indicates that the product is obsolete and notice has been given. Ambient Temperature Device Sensitivity vs. Date of status change: For a13011 latest version of this document, visit our website: What kind of magnets is the AllegroA sensible for?

There are no news items available for this product. I assumed that the differences were determined by me approaching and retracting the Neodymium magnet from the sensor. Click the image to view larger.
