As mentioned before, these modules are primarily designed for use with micro-controllers like the Arduino. Sir,I want to measure three phase current with arduinothe current sensor ACS will be applicable to acs712elc-20 or not?

In your AC current tutorial you say: If this were a 5 Amp module and the light bulb pulled 1 Amp, the output of the module would be 2. If you are connected as illustrated below, the output will raise.

The basic functional operation of each of these devices is identical. Is there any changes which I have to make in program? Sir, I am using this datasgeet in my power factor calculation project.


ACS712 Hall Current Sensor (20A)

S March 8, By continuing to visit this site you agree to accept cookies. In Arduino Used smooth average of 10 measurement no avail. Does anyone know the values for C1 and C2? If the light bulb shown in the picture above were disconnected, the output of the ACS module would be axs712elc-20a.

Now imagine the battery polarity reversed. Control with arduino and display to visualize current and voltage. Florin November 14, Your email address will not be published. Depending on the degree of precision you require, it could affect your measurements. Thanks Henry, You have a awesome web Page! Philippe July 21, Print Share on Tumblr.

The only difference is with the scale factor at the output as detailed below.

This should not be used in a permanent line voltage application. How we get to know that values which we are getting are true? More stable and sensitivity ratasheet mA. The ACS Current Sensors offered on the internet are designed to be easily used with micro controllers like the Arduino.

Hary January 7, The datasheet below will give you greater insight into the specifications and eatasheet of this manual.


Pay attention to the polarity at the load end of the device.

C1 is Cbyp in the ACS datasheet and should be 0. Hemalatha R June 26, The motor should pull about 17A. John January 2, Faiza sana November 19, Need advice, Best regards, Novan. If you connect it opposite of this picture, the output will decrease from the 2.

In arduino 1 digit approx 25mA. Don February 4, Leo December 3, Dave January 11, About the only hick up you would have is that the motor will draw a ton of current at start up and your current may be 5 times what it is in a steady state unless your driver is limiting it.

Thanks for the great tutorials.

Thank you for your nice tutorial and I want to ask you something Can this model read the current value of household electric appliance? I want to use this sensor to measure current of 14VDC motor.
