What is 433MHz receiver?
The 433 MHz RF transmitter and receiver module is a pair of small RF (i.e. radio-frequency) electronic modules used to send and receive radio signals between any two devices. The transmitter module sends the data from the transmitter end and the Receiver module receives that data at the receiver’s end.
How far can 433MHz transmitter?
Operating frequency: 433 MHz. Transmission Distance: 3 meters (without antenna) to 100 meters (maximum)

Can a Arduino be used as a RF transmitter?
These RF modules are very popular among the Arduino tinkerers and are used on a wide variety of applications that require wireless control. These modules are very cheap and you can use them with any microcontroller, whether it’s an Arduino, ESP8266, or ESP32. Specifications RF 433MHz Receiver Frequency Range: 433.92 MHz
What kind of transmitter does an Arduino Uno use?
The transmitter part consists of Arduino UNO and the 434 MHz Transmitter module. An external LED can be used but on board LED would be sufficient. The design of the Transmitter part is as follows. The RF Transmitter Module consists of 4 – pins: VCC, GND, Data and Antenna.
Where is the transmitter pin on an Arduino?
The data pin is connected to Pin 12 of the Arduino. An antenna similar to the transmitter module is connected to the antenna pin of the 434 MHz Receiver module. The on board LED which is connected to the 13 th pin of Arduino is used in the project although an external LED can always be used.
How does an AM radio work on an Arduino?
The AM radio behaves like a low pass filter on the PWM, so we get back the original audio signal there. This is only a proof of concept, so I kept it simple.
