Sale of this device alegro currently restricted to existing customer applications. Ambient Temperature Device Sensitivity vs. Two output sensitivity options are provided: 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? Do I have to process the raw data in order to get some better results?
There are no news items available for this product. High precision in output levels allegdo obtained by internal gain and offset trim adjustments made at end-of-line during the manufacturing process.
What kind of magnets is the AllegroA sensible for? 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. In the quiescent state no significant magnetic field: 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.
Read the data sheet. This classification indicates that the product is obsolete and notice has been given. The device should not be purchased for new design applications because of obsolescence in the near future. Conversely, the application of a north polarity —B magnetic field, in the same orientation, proportionally decreases the output voltage from its quiescent value.
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.
Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.
A1301 and A1302: Continuous-Time Ratiometric Linear Hall Effect Sensor ICs
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. Two device package types are available: For the latest version of this document, visit our website: Click the image to view larger. One of my friends recommended me to buy an Allegro A sensor.
Two output sensitivity options are provided: Supply Voltage Device Symmetry vs. Does a magnetic sensor “feel” fluctuations caused by approaching a metal piece to it? Date of status change: 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?
These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion. Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.
Before placing an order, the user is cautioned to verify that the information being relied upon is current. If yes, how can I test to find it out?

We’ll notify you when there are updates to this product. What do you mean by “slot”? 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. Thank you and have a nice week alleggo However, Allegro MicroSystems, Inc. August 30, Recommended Substitutions: My results show me random numbers varying from to which repeat at regular intervals.
Hall effect “switching” devices provide a digital output depending on the strength of the magnetic field. The information included herein is believed to be accurate and reliable.
Two device package types are available: These aa1301 make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.

Is there another way to wire the sensor? Linearity in percent is measured and defined as: Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. This proportionality is specified as the magnetic sensitivity of the device and is defined as: Units — — 4. 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.
Just a quick look at the spec suggests that the output is analogue, so digital read may not alegro much good – I would expect this device to give a voltage output on the output pin, so analogue read would be more appropriate. Therefore I would like to ask the kind forum members the following questions: A and A Datasheet.

Samples are no longer available. The A and A feature a ratiometric output. Are the results voltages or random numbers?
They are optimized to accurately provide a voltage output that is proportional to an applied magnetic field. They are optimized alegro accurately provide a voltage output that is proportional to an applied magnetic field.
