Seeed Grove Arduino 12v Relay Shield Electromagnetic Field Output?

Has anyone measured the electromagnetic field produced by a Grove 12v relay shield for Arduino uno? I’m using it for an infrared photobiomodulation application–similar to the Vielight–that uses the relay pulse to control flashing frequencies, so it’s important for me to know what kind of measurable EMF the relay pulse is outputting.

Hi there,

We can not found that Grove you said. Do you mind telling us about SKU or link of this Grove, so that we can solve the problem for you.

Best Regards,
