You could improve on this by using an op-amp to amplify the difference in voltage, and then output a single DC voltage corresponding to the current. My bench tests show the module to be very functional. Still would have the offset voltage, about 2 volts which you subtract out anyway. He also told me the data sheet for the ACS has some peek voltage circuit examples which I am going to datqsheet at right now.

With a purely resistive load, you should be able to establish the peak through timing.

Going to try the recified output The Allegro AC allows for high current measurements. Email Required, but never shown. I need to incorporate this into a circuit with another sensor, pressure transducer, hopefully I can run that pressure transducer and 2 of these Allegro ACS’s all on my 16F The problem I am seeing is the same problem I read about in this thread Just so I could see some real current other then a light bulb I am using a watt hair dryer which I am attempting to read how much current it is using.

That is a lot of current to draw from a battery unless it is a Lead-Acid cell cranking a car engine – even then it will only drive this sort of current datqsheet a short time. I came up with this routine that seems to be pretty stable.

You have to take many instantaneous measurements of both voltage and current and average them over time to get true power. This website uses cookies to enhance your experience. The thickness of the copper conductor allows survival of the device at up to 5x overcurrent conditions. The math seems right so far.


Again if anyones worked with one of these current sensor and has any good code examples they found worked I would not mind taking a peek at that.

The example code here should be modified to match your particular sensor. Allegro Support Just got off the phone with Allegro support who called me back after I emailed them just to confirm I wasn’t going crazy and I didn’t hook up something incorrectly and sure enough the Vout on the ACS will produce a sine wave proportionate to the current being used. At 60Hz it will occur 4. What I would like to know is shown in this videowhere you can see the current consumption. Trial and error and possible solution I’ve been trying allot of different approaches to my problem not wanting to give up and certainly not going to wait for someone to drop code in my lap.

Your PAUSE means you are only sampling a few times per second and so are unlikely to get the peak. Assuming a more or less pure sinewave, current follows the same pattern, However, for anything other than a pure resistive load, voltage and current will be out of phase and you may or may not have a sinewave.

Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. Digital power meters sample voltage and current several thousand times per dtasheet. I would like to know how could I know the current consumed from a battery using this sensoror other similar, using a microcontroller.

ADC input using a current transformer? Successfully using this sensor datsaheet applying the correct scale factor and offset. As always any help datasheet be appreciated. The ACS datashfet offered in four datwsheet. The device consists of a datasbeet, low-offset linear Hall sensor circuit with a copper conduction path located near the die. Total current consumed from a battery Ask Question.

I didn’t see that the person who was trying to do the same thing with the and ever came up with a solution. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage.

The Allegro ACS75x family of current sensors provides economical and precise solutions for current sensing in industrial, automotive, commercial, and communications systems.

Once you have the current consumed, you could subtract that from your battery’s capacity to obtain the ‘fuel level’, preferably padded with a good margin of safety. I will experiment with that and watch it closely. The device is fully calibrated prior to shipment from the factory.

The other two connections are to be placed in series with your load. The terminals of the conductive path are electrically isolated from the sensor leads pins 1 through 3. Members who have read this thread: According to the manufacturer’s website, this is a discontinued part: That part is not a problem.

This allows the ACS75x family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques.

This sensor is for A. Key in the picture below is the reminder to make solid connections. Madmanguruman, thank you very much, I don’t knew what was that sensor This larger scale factor, when properly designed for, can offer better measurement resolution.
