Wireless Module

[PrasadT1001]

Hello Everyone!
I am working on a project that requires a Wireless Tx-Rx.
The project that I'm working is a Railway Engine (a demonstrative model) that would be running on DC supply of 6-24Volts.
What I want to do is, the TX mounted at the Signal post should send a signal to the Locomotive.
Should I use two seperate Tx-Rx pairs for two different signals (No signal transmitted for Green, and two different frequencies for Red and Yellow).
The Receiver on the Locomotive should receive one of the signals, and accordingly the DC voltage will be stepped down to 6 V (for Yellow) and 0 V (for Red).

I want to reduce the amount and complexity of the programming as I am weak at it.
I would prefer to do it more of a Hardware-op'ed.

Will ASK or FSK work for this???

Thanks

Hello Prasad,

FSK RF modules are less prone to noise and hence, are preferred over ASK.

Using a multi-channel RF Transmitter, you can transmit your codes for the Yellow or Red color. However, the receiver must also be a multi-channel one, that keeps hopping between the 2 or all of the frequencies being used for communication. This will however increase your programming.

Else, in the simplest way, as you have mentioned, use two Tx-Rx pairs that communicate over two different frequencies, one for Yellow, the other for Red.

I would recommend modules from Analog, Embedded Processing, Semiconductor Company, Texas Instruments
