433MHz TX+RX Super-regenerative Wireless Transmitting Module FS1000A

433MHZ TX+RX SUPER-REGENERATIVE WIRELESS TRANSMITTING MODULE FS1000A

 

Manufacturer Part No: FS1000A/XY-MK-5V

 Its like using a serial port, except you don't need a wire.

You hook one side up to transmit and one side to receive and you can transmit from one Arduino to another wirelessly.

The signal is poor though and these are susceptible to interference.

FS1000A / RF Modules

• Setting the emitter’s DATA pin to HIGH will result in a radio transmission that will set the receiver’s DATA PIN to high.

• By doing so, it is obvious that a serial connection can be implemented, once a common baud rate has been defined.

• We’ll push bits to the transmitter’s DATA Pin, assuming we are in the supported baud rate interval, and the receiver will get the data we’ve sent over the radio (plus errors).

• Here is the signal on transmitter’s pin (CH1/yellow) and the signal collected at the receiver (CH2 / cyan):

 

• This shows that all we have to do is to hook the emitter to the AVR’s UART TX port, and the receiver to another AVR’s UART RX Port.
• We write some code to initialize the UART ports using the same baud rate, and we’re ready to exchange data.
• Here is a sample setup , with receiver connected to an Atmega8 board, showing data on a 2×16 LCD, and the emitter’s board with an Atmega128 and a Nokia 5110 LCD.
• The numbers on the two LCD’s match, as what this setup does is to increment an integer every second, and send it over the radio. So what we see on the 5110 LCD, we also see as V: number on the receiver’s screen.
