Need help in choosing sensor, microcontroller and relay board


I’m currently working on a project using sensor, microcontroller and relay. I was planning to use Arduino current sensor in circuit to detect its current usage and send it into Arduino microcontroller to determine the current range. The microcontroller will decide, if the current below 1A, nothing will happen, if above 1A, it will activate a relay which is Arduino supported relay board. I will do the programming for the range and decide. Can anyone help or provide me a link where I could buy all these 3 devices, which supported by each other?

I have found 3 devices myself, but I don’t know whether it can be used together. Please help me. Thanks.

    The current sensor seems to be DC sensor. Other than that, you should have no issues getting these to work together.

    ACS712 can be used for sensing both AC and DC current(#-Link-Snipped-#)
    The output of the sensor will be a small voltage. You can use an amplifier ckt (made using an op-amp) to amplify the voltage and read the value using the ADC of the Arduino.

    P.S: @#-Link-Snipped-# Stop posting incoherent replies.
