I have a sensor that gives off 4 volts when actuated and I would like to transmit it a distance to a light. So I found these RF Link Transmitter/Receiver at 434MHz:
The data sheets and instructions I've read all suggest a microcontroller. What I'm asking is this:
For the transmitter side of my project (sensor that gives off 4V), could I use an Analog/Digital converter instead of a microcontroller to convert the 4V? Would the transmitter send that signal?
I do have an Arduino Yun that I could use for the receiver side, but lets say I didn't have an Arduino, what would I be able to use to convert the data from the receiver? A Digital/Analog Converter?
Last Question: Would I need multiple transmitters/receivers for multiple sensors?
Thank you for your attention and any insight would be greatly appreciated. Thanks again!
