Downloads. application/pdf ACS Hall Current Sensor ; application/pdf ACS Schematic ACS Module uses the famous ACS IC to measure current using the Hall Effect principle. ACS Current Sensor Datasheet. The ACS sensor read the current value and convert it into a relevant voltage measurements is sensitivity (you can find it on the datasheet) which – for 5A.

I used the sensor whitout any load but still take current from dc power supply.
You have to acs datasheet the right range for your project since you have to trade off accuracy for higher datasheet datasgeet. Note that the value of scale factor changes for every module based on its range. The datasheet below will give you greater insight into the specifications and operation of this manual. In Arduino Used smooth average of 10 measurement no avail. Sir, I am using this sensor in my power datwsheet calculation project.
Hary January 7, Hary January 7, Using the same 5A module, the output would be 2. Sameer January 13, Value 0 current.
Thanks Henry, You have acs datasheet awesome web Page! Let us assume that the microcontroller you are using has a bit ADC and operates at 5V with a reference voltage of 5V for ADC conversion in that case the microcontroller will read the values of ADC from 0 to If the light bulb shown in the picture above were disconnected, the output of the ACS module would be 2. Found a solution on the internet that worked to make more stable: The motor should pull about 17A.
As mentioned before, these modules are primarily designed for use with micro-controllers like the Arduino.
ACS712 Current Sensor- 30A
Thank you for your nice tutorial and I want to ask you something Can this model read the current value of household electric appliance? This should not be used in a permanent line voltage application.
Florin November 14, Is it possible to replace the load LED by this motor? Does anyone know the values for C1 and C2? Jyk July 8, Is there any changes which I have to make in program?
Don February 4, Then the analog voltage given out by the ACS module is read using any analog pin on the Microcontroller. C1 is Cbyp in the ACS datasheet and should be 0.

I want to use datashfet sensor to measure current of 14VDC motor. This way the module enables us to measure both AC current and DC current. TL — Programmable Reference Voltage. Thank you for your nice tutorial and I want to ask you something Can this model read the current value of household electric appliance? Top menu About Us Contact.
Leave a Reply Cancel reply. Thanks for the great tutorials. The below diagram would be more illustrative. 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.

How we get to know that values which we are getting are true? Philippe July 21, If you are connected as illustrated below, the output will raise. I have not used this sensor in that type of application.
Dave January 11, If you are connected as illustrated below, the output will raise. These are the terminals through which the wire has to be passed. If you connect it opposite of this picture, the output will decrease from the 2. As mentioned before, these modules are primarily designed for use with micro-controllers like the Arduino. After calculating the output voltage we can, calculate the value of current from the voltage using the below formulae.
