Possible project with 433Mhz RF Transmitter + Receiver Module Link Using multiple analog sensors Answered

Is it possible to send multiple sensor readings via through a 433Mhz RF Transmitter + Receiver Module Link?..Meaning, assume that I have a three Flex sensors on the transmitter side and three servos on the receiver side. I have the project almost complete however I would like to make it wireless with these rf modules.

When you bend a flex sensor its corresponding servo motor will turn depending on how far the sensor is bent. I do not know if this is possible using these modules since there are multiple flex sensors and they are analog (I'm not sure if analog is the correct term but what I mean is since the sensors will output an array of values I don't know if it will work since its not digital)

If anyone knows if this is possible please let me know and also if you can I would need help with the code, I have never made anything wireless before but it seams really neat.

Thanks to all those who reply!

Timing is your issue and bandwidth.
Most receivers you find work analog, which means one signal at a time.
Only way I know to address that problem would be to combine the sensor side befor sending them.
Like adding the values into a hex string or base 64 encoded string and to transmit this in set intervals.
Sending it around every 50ms should be more than sufficient and leave enough CPU time to do the required calculations.
