Dry-Reed Relay Problem


#1

Hi,

I have a quick question regarding the Dry Reed Relay http://www.seeedstudio.com/wiki/Grove_-_Dry-Reed_Relay

Is this relay an output only sensor or can it be used in Input (NO) mode?

By that I mean, can it detect the closure of a circuit, for example the opening and closing of a magnetic door contact connected to J2?

Thanks,

Dave

Hi Dave,
The Dry read relay is an output only device that can only be sent signals to turn it on/off.

If you are looking for something that would detect the opening and closing of a magnetic door contact, you should have a look at this: https://www.seeedstudio.com/item_detail.html?p_id=744.
