Date of status change: I have used the MAX command to get this far but I xcs754 can’t seen to figure out how to get or keep track of a reading that is not fluctuating with the wave of the AC. The current is rising and falling with the AC so I darasheet not getting a steady reading. The device package allows for easy implementation by the customer. Sign up or log in Sign up using Google.

Samples are no longer available. Each offered range is available as either a uni-directional sensor or a bi-directional sensor.

The math seems right so far. The device consists of a precision, low-offset linear Hall sensor circuit with a copper conduction path located near the die. What current range do you intend to sense?

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. Your PAUSE means you are only sampling a few times per second and so are unlikely to get the peak. The device is fully calibrated prior to shipment from the factory.


I will experiment with that and watch it closely. The heavy gauge leadframe is made of oxygen-free copper. In order to measure the current consumption or the battery’s state of charge, you need to integrate current over time. When I turn it on the current follows the AC and my reading goes from This is equal to 2.

The thickness of the copper conductor allows survival of the device at up fatasheet 5x overcurrent conditions. Sign up using Email and Password. The terminals of the conductive path are electrically isolated from the sensor leads datashest 1 through 3. 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 for a short time.

ADC input using a current transformer? Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer. The Allegro AC allows for high current measurements.


The uni-directional ac7s54 measure current in one direction only and thus allow for a larger scale factor. Key in the picture below is the reminder to make solid connections. Digital power meters sample voltage and current several thousand times per second.

You have to take many instantaneous measurements of both voltage and current and average them over time to get true power. 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 datashert a watt hair dryer which I am attempting to read how much current it is using.

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. Assuming datasheeg 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. What I would like to know is shown in this videowhere you can see the current consumption.

The table below is derived from the ACS Datasheet.
