For the latest version of this document, visit our website: Units — — 4. Samples are no longer available. Because I get the same results when I “read” both al,egro empty slot and the slot with the sensor, is it possible that my sensor is broken?

What kind of magnets is the AllegroA sensible for? Thank you and have a nice week ahead!

Two device package types are available: There are no news items available for this product. These features make the A and A ideal for use in position sensing systems, for both linear target motion a1310 rotational target motion.

One of my friends recommended me to buy an Allegro A sensor.

In the quiescent state no significant magnetic field: Sale of this device is currently restricted to existing customer applications. Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. 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.

Two output sensitivity options are provided: Therefore I would like to ask the kind forum members the following questions: 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 to give a voltage output on the output pin, so analogue read would be more appropriate.


Ambient Temperature Device Sensitivity vs. If yes, how can I test to find it out?

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 sensor.

August 30, Recommended Substitutions: Before placing an order, the user is cautioned to verify that the information being relied upon is current. Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.

Allegro A1301 SIP-3 Hall-effect sensor 2.5mV/G

Two output sensitivity options are provided: The A and A feature a ratiometric output. My results show me random numbers varying from to which repeat at regular intervals.

Linearity in percent is measured and defined as: The information included herein is believed to be accurate and reliable. Hello I think you need to go back to the basics Have you looked at the data sheet for this device? The Allegro site suggests that this is an end of life device, so maybe not the best choice.

My goal is to make a device that can be used to sense some metal approaching it. We’ll notify you when there are updates to this product. In reality, after modifying the sketch and adding an extra variable allero read an unused slot, I realized that the results were similar in nature. Click the image to view larger. Integrating the Hall sensing element and the amplifier on a single a3101 minimizes many of the problems normally associated with low voltage level analog signals.


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

Please contact the Allegro Marketing department for additional information. 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. The on-chip output stage is designed to provide linear output at a supply voltage of 5 V.

What do you mean by “slot”? Allegro are generally pretty good at application notes, so I would start there, before even starting with code. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.

Are the results voltages or random numbers? Is there another way to wire the sensor? Although the application of very high magnetic fields does not damage these devices, it does force their output into a nonlinear region.

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

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. Supply Voltage Device Symmetry vs.
