ACS723 Low Current Sensor Project Guidance

Dear All,

( https://cdn.sparkfun.com/assets/2/3/c/8 … Sensor.pdf )

I new on this forum and as well as in electronic. Currently i would like to design of ACS723 low current sensor with filter circuit. My intention to use AC or DC between 50mA to 2A.

Total 10 sensors use in same board. The filter circuit given by SparkFun is able to work or need to isolate any special circuit? I hope some of your able to guide me.

i try to use some simulation software was not success. At the movement i try to buy component, in-order to order pcb board please anyone advice.

Thanks

Much Appreciate

I’m not exactly sure what you’re asking but I can say that the current sensing side of the board and the boards power input and analog output are isolated from each other.

Dear Sir,

Thanks and appreciate for respond. My question it same filter circuit for for ACS-723 can i make more sensor in same board. Which it same Vcc same ground and the primary source are same, All sensor 1&2 same main source 3&4 out put are go different channel. all sensors analogue output are go individual to CPU.

Example of following items are connected in parallel, i would like to ask it that any effected to circuit since all sensors in one board.

C3 Vcc to ground 0.1uF,

C4 Vcc to ground 0.1uF

BW_SEL Vcc to ground resistor 4.7k

:?

Thanks Regards

If you’re asking if you can use multiple SparkFun boards together and parallel the power supplies for them, yes, that is OK. You just can’t parallel the outputs from the boards, those need to go to separate analog inputs on your system.

If you’re asking about building your own board based on our schematic, I’m afraid I can not assist you with that.

Thanks Sir,

Firstly i want to build the board by my self, due to narrow space.

Now I plan to buy sensors board from sparkfun and add on my main board.

Thanks Regards
