The 433MHz RF Transmitter and Receiver pair provides a simple and cost-effective solution for wireless communication. The pair consists of two separate modules: a transmitter and a receiver. The transmitter module takes a digital signal and wirelessly sends it using a 433MHz carrier frequency. The receiver module, tuned to the same frequency, captures the transmitted signal and converts it back into a digital signal that can be processed by a microcontroller or other digital logic.

These modules are known for their simplicity and are often used with microcontrollers like Arduino, Raspberry Pi, or PIC. They are suitable for applications that require a one-way communication link over a short to medium range.

Specifications

Transmitter Module (the larger, rectangular board on the left):

* Operating Voltage: Typically 3V to 12V DC. The higher the voltage, the greater the transmission power and range.

* Operating Current: Varies depending on voltage, but usually around 10-20mA.

* Operating Frequency: 433.92MHz (commonly referred to as 433MHz).

* Modulation Mode: ASK (Amplitude Shift Keying) or OOK (On-Off Keying).

* Transmission Power: Typically 10mW to 25mW.

* Transmission Distance: Up to 100 meters in open air, but this is highly dependent on power supply, antenna length, and environmental conditions.

* Pinout:

* VCC: Power supply input (3V-12V).

* GND: Ground.

* DATA: Data input pin for the digital signal to be transmitted.

* ANT: Antenna connection point (often a wire soldered to the board).

Receiver Module (the smaller, square board on the right):

* Operating Voltage: Typically 5V DC.

* Operating Current: Around 4mA to 5mA.

* Operating Frequency: 433.92MHz (fixed).

* Modulation Mode: ASK/OOK.

* Sensitivity: High, typically around -105dBm.

* Pinout:

* VCC: Power supply input (5V).

* GND: Ground.

* DATA: Data output pin for the received digital signal.

* ANT: Antenna connection point (often a coiled wire on the board, but can be a separate wire).

Common Features:

* Low power consumption: Especially the receiver module, making it suitable for battery-powered projects.

* Simple interface: Designed to be easily connected to microcontrollers.

* Cost-effective: One of the most affordable wireless communication solutions.

* Limitations:

* One-way communication: This is a simplex system; communication is from transmitter to receiver only.

* Prone to interference: Can be affected by other RF signals in the 433MHz band.

* No error correction: Requires additional software-based protocols (like Manchester encoding or other data packets) to ensure reliable data transfer.

* Fixed frequency: Both modules operate on the same fixed frequency.
