Relay with ACS712

[Dheeraj]

@doblanch i'm in process of completing the sketch and will share it with you once finished.

here's the finished product :)

re quite sufficient in packing all things together

thanks

How far have you been with the ACS712 ?

@epierre said:

able to calculate the wattage of 2 loaded devices to a rough level.. p = v x i. ..still WIP.

attempt over last week , circuit board with 2x relay actuator and hall current sensor ( acs712 ) and step down transformer. The most challenging part is how to pack your creation in a nice box. ;)

Nice work.Can you show how you wired this and maybe share your sketch ?

[epierre]

@Dheeraj yes can you share more of what you did ? thanks !

[Dheeraj]

@epierre .. nothing much .. used relay to control 2 devices and tried to calculate the power consumed ( in watts ) assume the input voltage is ~220v.

Quick question but where did you get that enclosure from and the multi type plug sockets. They look modular?

[epierre]

@Dheeraj have you something to share about the ACS712 and voltage consumption, I could help too by trying to make my own tests ? I already have the chip.

Hi, can You share your sketch? Thank You.

hello,

thank for the picture.

As the others above, I would be very interested to know where you get that enclosure from and if you can share the sketch.

Thanks

Seems to be a surface mount Crabtree box, which is a brand available in the UK.

I found a reference to something like this on a FARNELL site:

From what I understand the ACS712 is affected by magnetic interference. Do you think the close proximity to the relay will skew the readings?

@Shivanand-Chanderbally I recently finished a node using the acs712 and found it to be very sensitive to nearby magnetic fields. It is best to have it as far away from these as you can.
