Merci d'avance 6 replies (/member/Khzalsabila/) Khzalsabila (/member/Khzalsabila/) 1 year ago Reply Upvote hello, thanks for your writing. now im learning how to measure power factor using arduino and i am going to use acs712 current sensor module. but as i read your post and your comment, you recomended CT as it more safer. i have read about CT to find why its much safer but i can't find the idea. can you please help me out why CT is more safer and what about acs712? thankyou 1 reply (/member/Vasu_S4/) Vasu_S4 (/member/Vasu_S4/) 2 years ago Reply Upvote can we apply the xor gate logic with non-linear loads once we get the zero crossing detector output? 2 replies (/member/dnyaneshvarsalve/) dnyaneshvarsalve (/member/dnyaneshvarsalve/) 2 years ago Reply Hi, thank u for great tutorial. can you please add a more simplified circuit diagram something like what i have given as example. Because fritzing diagram is confusing me with the ground connections.
