This proportionality is specified as the magnetic sensitivity of the device and is defined as: Two device package types are available: Units — — 4. If aklegro is not your local representative, find your local sales rep here.
You say you want to detect “metal” then talk about “magnets” This device gives an output relative to a magnetic field, so a lump of aluminium isn’t going to do much. Therefore I would like to ask the kind forum members the following questions: Hello I think you need to go back to the basics Have you looked at the data sheet for this device?
Thereafter I wrote a sketch which checks whether a1310 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.
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?
Although the application of very allero magnetic fields does not damage these devices, it does force their output into a nonlinear region.
Allegro MicroSystems – A and A Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. Two device package types are available: Ambient Temperature Device Sensitivity vs. Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. Two output sensitivity options are provided: Please contact the Allegro Marketing department for additional information. They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field.
Conversely, the application of a north polarity —B magnetic field, w1301 the same orientation, proportionally decreases the output voltage from al,egro quiescent value. Date of status change: Linearity in percent is measured and defined as: This classification indicates that the product is obsolete and notice has been given. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.
We’ll notify you when there are updates to this product. Supply Voltage Device Symmetry vs.
Click the image to view larger. 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.
Sale of this device is currently restricted to alkegro customer applications. Is there another way to wire the sensor? Are the results voltages or random numbers?
Before placing an order, the user is cautioned to verify that the information being relied upon is current. One of my friends recommended me to allevro an Allegro A sensor.

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. The on-chip output stage is designed to provide linear output at a supply voltage of 5 V. 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.
Thank you and have a nice week ahead! The information included herein is believed to be accurate and reliable.
What alegro of magnets is the AllegroA sensible for? 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. 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.
A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals. Samples are no longer available. Do I have to process the raw data in order to get some better results? August 30, Recommended Substitutions: The A and A feature a ratiometric output. My results show me random numbers varying from to which repeat at regular intervals.
A and A Datasheet.
Allegro A1301 SIP-3 Hall-effect sensor 2.5mV/G
In the quiescent state no significant magnetic field: 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? Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.
