The only way to test them would be to try one of the sample programs on the Parallax webstore page for the product. If you had a 433MHz receiver with an oscilloscope output or a spectrum analyzer, you could tell if the transceiver is transmitting. Improving range of 433MHz RF modules The antenna that you use for both the transmitter and receiver can really affect the range you’ll be able to obtain with these RF modules. In fact without an antenna you’d be lucky to communicate over a distance of more than a meter. I cannot determine whether the RF Receiver or Transmitter works. I want to see if my RF Transmitter gives an output, but I do not own an oscilloscope to view it's waves. I've seen this answer, but it only shows if the Arduino is sending data to the RF Transmitter. Is there any alternative way to check if the RF Transmitter works or not? Thanks! Other RF modules: HC12, nRF24l01, nRF905 . Other Wireless options: Bluetooth, Lora, ESP8266, GSM, Xbee . Where to use 433 MHz RF modules: The 433MHz wireless module is one of the cheap and easy to use modules for all wireless projects. These modules can be used only in pairs and only simplex communication is possible.
