Hi everyone.
I was wondering if anyone might have suggestions for some type of transmitter / receiver system I could use to remotely control a relay. Ideally, I'd like to be able to press a pushbutton (or initiate a contact closure) on a transmitter and activate a relay on the receive end. I don't really have the know-how to build a transmit / receive system from scratch, so I'd prefer some sort of pre-manufactured option or some kind of kit.
Here are a few specifics about what I'd need:
I'd need something that uses wireless RF, as opposed to using an IR beam. The range doesn't need to be too long...200' or so should be more than sufficient.
I'd like a setup where initiating the pushbutton or creating a contact closure on the transmit end initiates a momentary relay closure on the receive end (as opposed to latching the relay on or off).
The relay can be light duty and as simple as SPST. I'd likely be passing 5 - 10 VDC at < 100 mA through the contact, so I don't by any means need a heavy duty relay.
I'd likely be mounting the transmitter and receiver in project boxes, so the smaller, the better. Also, I'd like to be able to power the transmitter and receiver using standard batteries.
Thanks to anyone who might be able to offer some suggestions!
