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

Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. 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. A and A Aplegro. Allegro are generally pretty good at application notes, so I would start there, before even starting with code.

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.

Date of status change: Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it? We’ll notify you when there are updates to this product. Thank you and have a allebro week ahead!

Do I have to process the raw data in order to get some better results? Are the results voltages or random numbers? The device should not be purchased for new design applications because of obsolescence in the near future.


Ambient Temperature Device Sensitivity vs. Hello I think you need to go back to the basics Have you looked at the data sheet for this device?

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

They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. The information included herein is believed to be accurate and reliable. Is there another way to wire the sensor?

Because I get the same results when I “read” both an empty slot and the alleggo with the sensor, is it possible that my sensor is broken? Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.

The A and A feature a ratiometric output. What kind of magnets is the AllegroA sensible for? The Allegro site suggests that this is an end of life device, so maybe not the best choice.

Before placing an order, the user is cautioned to verify that the information being relied upon is current. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Conversely, the application of a north allegfo —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.

Two output sensitivity options are provided: Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.

1a301 goal is to make a device that can be used to sense some metal approaching it. 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. If yes, how can I test to find it out? Two output sensitivity options are provided: 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: This classification a13301 that the product is obsolete and notice has been given. Samples are no longer available. For the latest version of this document, visit our website: In the quiescent state no significant magnetic field: 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.

My results show me random numbers varying from to which repeat at regular intervals.
