mustafasei Posted September 19, 2018 Share Posted September 19, 2018 I have a voltage sensor ZMPT101b and I want to measur the AC voltage of normal home socket Can I use the arduino uno analog input directly for that?? Also same for current sensor ACS712 I want to read Thanx Link to comment Share on other sites More sharing options...
JColvin Posted September 19, 2018 Share Posted September 19, 2018 Hi @mustafasei, I have moved your question to a more appropriate section of the Forum. Those of us at Digilent haven't used either of those sensors, but glancing at their datasheets, they should both be electrically compatible with an Arduino Uno. Be sure to take appropriate caution when measuring voltage and current of a home electrical outlet though and know that I haven't verified whether or not those two modules are electrically safe to use with it. Thanks, JColvin Link to comment Share on other sites More sharing options...
mustafasei Posted October 5, 2018 Author Share Posted October 5, 2018 Hi LCcolvin thank you for your advice ,don't worry my friend i'm a high voltage electrical engineer. i have connect the voltage sensor to the arduino and used the analog input channel to measure the voltage but the output always give as 2.5 dc volt even when there is no ac voltage applied on the sensor . as I know from data sheet of the voltage sensor the output is DC offset so i think I have to use a filter which I don't know to build it any idea please Link to comment Share on other sites More sharing options...
