What is the maximum current this circuit can measure? From the trend line I can see for maximum 5v reading it can go for max of 10 amps reading. Please confirm.
This is a very cheap and effective way to remotely monitor older people living alone. Monitor toilet flushes and usage of kettle is a good indicator all is well. Some things in life we do reguarly, making tea and going to the loo is one of them
hello, i've been trying to find instructables like yours. i'm just curious how does the ACS712 limits the voltage and the current from an AC source. i have read other projects which do not recommend ACS712 for ac sources for which it can damage the arduino. thanks for your reply :)

HI CAN YOU EXPLAIN CALIBRATION PART!how exactly you calculated intercept and slope in excel?
Internet of Things Toilet Uploads Events to the Cloud (Raspberry PI)
Made with AdaFruit Wifi Feather and OLED wing board and 20A ACS712 sensor.Feather is running a 12bit ADC.Not final packaging but proto with showing Amps on OLED screen against Multimeter.
Hi,This did not work for me. I have an Mega 2560 Sainsmart (runs all arduino code) and if I use a baud rate of 57600, everything printed out is symbols and wingdings. Baud of 9600 shows amps at 0.23 and sigma at 8.20 when no current is flowing.When I close circuit, i get the same values. I have all libraries called, just seems the code example may not work for my baud rate?any help would be appreciated :/
hi, could you send your Code also to my pm?Thanks a lot!Holger - HolgerP
Can you send me a code .. PM? :) - SlowSoft
Model Rocket Launch Controller added to Power Tool Battery Charger
Hello!I don't really care about measure amps, I just want to make sure all my water and air pumps are getting 127v, and if not, I can turn on the power gen.Do you think this ACS712 can serve that purpose?Thanks!
how about the wave from acs712? can i see?
Can you please explain the code ?
In the source sketch is used 1024, and why do not you use the coefficient?
Thank you for your reply. But as my project is based on PIC18F4550 Micro-controller, can you provide me code or reference for the same - TanmayG6
Thank you. This helpde me for my project. can you please tell me how to interface/connect acs712 with pic18f4550 and also the code for the same.
This code you have written is for which controller ?Can you please provide code for pic18f4550 or any source or reference for the same.
