433 MHz RF Wireless Transmitter
433MHz wireless module is one of the cheap and easy to use modules for all wireless projects. These modules can only be used in pairs and only one-way communication is possible. Meaning the transmitter can only transmit information and the receiver can only receive it, so it can send data from point A to B and not from B to A.
These RF modules are Arduino projects It is very popular among. 433MHz receiver/receiver modules are used in a wide variety of applications requiring wireless control.
These modules are very inexpensive and you can use them with any microcontroller (MCU), be it an Arduino, ESP8266 or ESP32.
So if you are looking for simple wireless communication to transmit information over a short distance, RF cards may be the right choice.
