Allegro A1301 SIP-3 Hall-effect sensor 2.5mV/G
a130 The device should not be purchased for new design applications because of obsolescence in the near future. The information included herein is believed to be accurate and reliable. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.
Are the results voltages or random numbers? There are no news items available for this product.

This classification indicates that the product is obsolete and notice has been given. Low-noise output Fast power-on time Ratiometric rail-to-rail output 4.
If this is not your local representative, find your local sales rep here. Low-noise output Fast power-on time Ratiometric rail-to-rail output 4. My results show me random numbers varying from to which repeat at regular intervals. Integrating the Hall circuit and the amplifier on a single chip minimizes many of the problems normally associated with low voltage level analog signals.
The on-chip a1031 stage is designed to provide linear output at a supply voltage of 5 V. Hello I think you need to go back to the basics Have you looked at the data sheet for this device? 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.
Is there another way to wire the sensor? Please contact the Allegro Marketing department for additional information. What do you mean by “slot”?
This proportionality is specified as the magnetic sensitivity of the device and is defined as: I assumed that the differences were determined by me approaching and retracting the Neodymium magnet from the sensor. In the quiescent state no significant magnetic field: Two output sensitivity options are provided: The Allegro site suggests that this is an end of life device, so maybe not the best choice.
For the latest version of this document, visit our website: Linearity in percent is measured and defined as: Hall effect “switching” devices provide a digital output depending on the strength of the zllegro field. These features make the A and A ideal for use in position sensing systems, for both linear target motion and rotational target motion.
A and A Datasheet. 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. Click the image alleyro view larger.
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. 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.
Integrating the Hall sensing element and the amplifier on a single chip minimizes many of the problems normally associated with low voltage a101 analog signals.

Samples are no longer available. Do I have to process the raw data in order to get some better results?
