How to insert a 12V DC micro pump into a relay using arduino?

Other Hardware General Electronics

Hey guys, I am doing a project that requires inserting a 12V DC micro pump into a relay using arduino. I am a amateur at arduino. I am using a relay module(SRD-05VDC-SL-C) and a 12V DC micro pump that can be connected to the relay. All comments are greatly appreciated. Thank you!

If you want to insert the pump into the relay you need to open up the relay and miniaturize the pump and fix it inside the relay.... But I don't think that's what you want...

To control the pump, just use Google. It's the same as any other device. But I think this says it all:

Have a look at this....

By the way, when I Googled that part number I found the relay itself, not a module as in relay on aboard with other electronics. Septillion's response implies he thought you meant the latter, so it might be better if you clarified if you have the simple relay or a the relay-on-a-board.

Datasheet?

Why do you think you need a relay. Isolation?
Maybe you can drive the micro pump directly from the Arduino with a mosfet or NPN transistor.
How big is the micro pump (current).

The datasheet is quite limited but nevertheless the link is here:

Hey guys, first of all, i'm just an amateur at arduino and coding. I am doing a project that requires a micro pump, relay and arduino. So I got stuck at the part whereby, i have to connect the wires of a 12V DC pump into a relay. It is not a relay module. The relay is a SRD-05VDC-SL-C and this link is the datasheet for the relay: http://www.datasheet-pdf.com/datasheet/Songle/720556/SRD-05VDC-SL-C.pdf.html

Thanks

I think it needs 71mA at 5V. You need a transistor to activate the relay.
As in the picture in the first post of this topic : http://forum.arduino.cc/index.php?topic=308620.0
Do you know which pins are for the 5V coil and which for the switching contacts ? There are other datasheets that show it.
