Wiki of Grove - Serial RF Pro
Hi - you answered a question saying that the max open air distance is 100m but it is listed above as 1km. Which one is it?
Its transmission distance is over 1km,and anterior answer is early product.
Hi there, GROVE is a serial products of our company, all the parts have 4pin interface, called grove interface .Here is a link , you can read the wiki of each part.

Sorry that we do not sell UART to/from USB cable for this product , if you want to bug can search here : http://www.seeedstudio.com/dep...
In an open area, the distance can be 100m at most.
Can i make a kind of "RF proximity sensor" with this?
Example: one unit travel with me and when i get close to a receiver base(another unit) an action is triggered at base.
Is this possible or should i use another cheap solution?
good idea, but notice the transmission distance can be upto 600m and varies with air conditions , tempratures and so on .
actually, i think the bluetooth would be better for your project.
Now that I received my second Serial RF Pro, I'm ready to start my project. I want to know before soldering it, if this wire, with its lenght, is enought or would you recomend me to solder something bigger? It seems so small compared to the pig tail co
hey,just solder the antenna to the pad,it's enough.
Hi Daniele Canziani.It is feasible in theory.
Yes,you can control multiple transceivers simultaneously.
