Ac current measurement using acs712 hall effect current sensor and arduino.
Ac current measurement using arduino and acs712.
Acs712 current sensor can measure both direct and alternating current.
You just need make change in code but the rest of the concept.
Eliminating the special signal conditioning circuit board instead we re going to use the runningsta.
Hello and welcome to another tutorial this one is about measuring alternating current ac using acs712 i m using the 30amps version which is acs712 30a and our lovely arduino uno board i tried to add an oled screen but unfortunately ended up breaking it while shooting the tutorial so i switched to the lcd but below you ll find the.
Please be careful if you re using the power line.
You can not use the below formula to measure alternating current with acs712 hall effect current sensor.
As shown on lcd first line is showing measured adc value and second line is showing voltage and third line is showing measured which is exactly the same current we measured with virtual ampere meter in proteus.
Simplified arduino ac current measurement using acs712 hall effect sensor.
For this post tutorial project i am going to measure only dc current.
Formula which i derived and explained in the tutorial is only for direct current measurement.
