If there is no load but there are some dataseet meassured not zero, make sure the ground from acs to s also connected with arduino. Sameer January 13, If you connect it opposite of this picture, the output will decrease from the 2. Hemalatha R June 26, Leo December 3, In your AC current tutorial you say: The ACS Current Sensors offered on the internet are designed to be easily used with micro controllers like the Arduino.

Jyk July 8, Hary January 7, Sir, I am using this sensor in my power factor calculation project.

The datasheet below will give you greater insight into the specifications and operation of this manual. Because I am not aware of any certifications for the device to indicate that it is safe for high voltage applications. It should not be used near significant magnetic fields. Thanks for the great tutorials. Found a solution on the internet that worked to make more stable: Once connected, the output would be scaled to the current drawn through the bulb.


Need advice, Best regards, Novan. C1 is Cbyp in the ACS datasheet and should be 0. Thanks Henry, You have a awesome web Page! The Vcc of the circuit is 5.

ACS712 Current Sensor User Manual

The motor should pull about 17A. John January 2, MRC November 9, It will only set you back a few dollars.

Carl Bartlett June 16, Your email address will not be published. As mentioned before, these acs712elc-20x are primarily designed for use with micro-controllers like the Arduino.

Is it possible to replace the load LED by this motor? In Arduino Used smooth average of 10 measurement no avail. I have not used this sensor in that type of application. Control with arduino and display to visualize current and voltage. Values currentsensor jumped to much.

Does anyone know the values for C1 and C2? Florin November 14, Raja May 11, This should not be used in a permanent line voltage application. By continuing to visit this site you agree to accept cookies. Print Share on Tumblr. I used the sensor whitout any load but still take current from dc power supply. Faiza sana November 19, Leave a Reply Cancel reply. The datasneet functional operation of each of these devices is identical. Al Mansur December 27, While the data sheet does not discuss phase shift, it does discuss rise time.


I see a whole lot of challenges.

ACS712 Hall Current Sensor (20A)

S March 8, Do you think it is possible? Don February 4, Thank you for your nice tutorial and I want to ask you something Can this model read the current value of household electric appliance? If this were a 5 Amp module and the light bulb pulled 1 Amp, the output of acs72elc-20a module would be 2.

Dave January 11, The only difference is with the scale factor at the output as detailed below.

Using the same 5A module, the output would be 2. Value 0 current. More stable and sensitivity of mA.
