I would like to use a current sensor in my Arduino circuit. The sensor will read the current passed through it and then the arduino will react accordingly. For example, if the current is less then 5 amps do this or if the current is more then 8 amps do that. i am going to monitor the current flow of a pump and the different current readings will alert me to potential issues with plugged intake, broken pipe etc. I would like to monitor an A/C current of up to 12 amps. Which current sensor will best meet my needs? When I am testing, how can I create a dummy load of 5 amps and 8 amps as those will be the two trigger points for my project. I am using an arduino mega 2560 r3.
Thank you in advance
