More stable and sensitivity of mA. Is there any changes which I have to make in program? John January 2, Philippe July 21, Dave January 11, Hary January 7, It will only set you back a few dollars. About acs7122elc-20a 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 avs712elc-20a is limiting it.

Is it possible to replace the load LED by this motor? Is there any phase error between input current and output voltage? Faiza sana November 19, C1 is Cbyp in the ACS datasheet and should be 0. Raja May 11, Hi, I would like to use this sensor in the following case: If the light bulb shown in the picture above were disconnected, the output of the ACS module would be 2.


I see a whole lot of challenges. Hemalatha R June 26, Do you think it is possible? While the data sheet does not discuss phase shift, it does discuss rise time.

ACS712 Hall Current Sensor (20A)

Thanks for the great tutorials. Your acs712elc-20z address will not be published. Using the same 5A module, the output would be 2. Control with arduino and display to visualize current and voltage.

ACS Current Sensor- 20A

In your AC current tutorial you say: The basic functional operation of each of these devices is identical. This website uses cookies to enhance your experience. Because I am not aware of any certifications for the device to indicate that it is safe for high voltage applications. In Arduino Used smooth average of 10 measurement no avail. Print Share on Tumblr. If you are connected as illustrated below, the output will raise. Sameer January 13, Leave a Reply Cancel reply. Depending on the degree of precision you require, it could affect your measurements.

I have not used this sensor in that type of application. The ACS Current Sensors offered on the internet are designed to be easily used with micro controllers like the Arduino. Al Mansur December 27, If this were a 5 Amp module and the light bulb pulled 1 Amp, the output of the module would be 2. MRC November 9, Does anyone know the values for C1 and C2? Thanks Henry, You have a awesome web Page! I used the sensor whitout any load but still take current from dc power supply.


In arduino 1 digit approx 25mA. The only difference is with the scale factor at the output as detailed below.

If there is no load but there are some value meassured not zero, make sure the ground from acs to s also connected with arduino. Thank you for your nice tutorial and I want to ask you something Can this model scs712elc-20a the current value of household electric appliance?

Sir, I am using this sensor in my power factor calculation project.

Pay attention to the polarity at the load end of the device. The Vcc of the circuit is 5. The datasheet below will give you greater insight into the specifications and operation of this manual.

dtaasheet Values currentsensor jumped to much. Once connected, the output would be scaled to the current drawn through the bulb. Found a solution on the internet that worked to make more stable: The motor should pull about 17A.

Value 0 current. Sir,I want to measure three phase current with arduinothe current sensor ACS will be applicable to measure or not?
