Description
The RF 433MHz Transmitter/Receiver Module – Wireless Pair is a cost-effective radio frequency solution for short-range wireless communication, widely used in Arduino, Raspberry Pi, and ESP32 projects. This pair consists of a transmitter module (e.g., MX-FS-03V or similar) and a receiver module (e.g., MX-05V or similar), operating at a 433MHz frequency within the ISM band, requiring no special license. The transmitter uses Amplitude Shift Keying (ASK) modulation, sending digital data via a SAW-stabilized oscillator when the DATA pin is HIGH (3-12V, typically 5V, with higher voltage boosting range), with a transmission power of up to 25mW. The receiver, requiring a stable 5V DC supply, features a superheterodyne or super-regenerative design with a sensitivity of -105dB, decoding the transmitted signal into a digital output on its DATA pin. With a typical range of 20-100m in open space (reduced to 30-50m with obstacles, extendable to 100m with a 17cm antenna), it’s ideal for remote control applications like garage doors, smart home devices, or wireless sensors.
