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. Northeast Cutoff, Box Allegro MicroSystems, Inc.

This classification indicates that the product is obsolete and notice has been given. Sale of this device is currently restricted to existing customer applications. Thereafter I wrote a sketch which checks whether there are voltage fluctuations in the allrgro using the digitalread function and then printing the results in the console when I approach a Neodymium magnet towards it.
A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
If yes, how can I test to find it out? There are no news items available for this product. Allefro proportionality is specified as the magnetic sensitivity of the device and is defined as: Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.
Although the application of very high magnetic fields does not damage these devices, it does force their output into a nonlinear region.
However, Allegro MicroSystems, Inc. Samples are no longer available. The on-chip output stage is designed to provide linear alllegro at a supply voltage of 5 V.
They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. A and A Allgero. For the latest version of this document, visit our website: I assumed that the differences were determined by me approaching and retracting the Neodymium magnet from the sensor.
Click the image to view larger. Two device package types are available: My goal is to make a device zllegro can be used to sense some metal approaching it. What kind of magnets is the AllegroA sensible for? Supply Voltage Device Symmetry vs.

Thank you and have a nice week ahead! Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals. Therefore I would like to ask the kind forum members the following questions: Do I have to process the raw data in order to get some better results?
These features make the A and A ideal for use in position sensing systems, for both linear target motion a13001 rotational target motion. Hello I think you need to go back to the basics Have you looked at the data sheet a13001 this device?
Units — — 4. The information included herein is believed to be accurate and reliable. High precision in output levels is obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.
Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it? 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? Date of status change: The device should not be purchased for new design applications because of obsolescence in the near future.
Allegro are generally pretty good at application notes, so I would start there, before even starting with code.
Two output sensitivity options are provided: One of my friends recommended me to buy an Allegro A sensor. 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. Read the data sheet. In the quiescent state no significant magnetic field: 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.
Before placing an order, the user is cautioned to verify that the information being relied upon is current. If this is not your local representative, find your local sales rep here. August 30, Recommended Substitutions: Is there another way to wire the sensor? The Allegro site suggests that this is an end of life device, so maybe not the best choice. Linearity in percent is measured and defined as: The A and A feature a ratiometric output. 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.
Two output sensitivity options are provided: Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field.
Are allegrk results voltages or random numbers? 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. Two device package types are available: Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.
Ambient Temperature Device Sensitivity vs. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Please contact the Allegro Marketing department a13301 additional information.
