How It Works
The transmitter module sends data wirelessly to the receiver using ASK modulation. When paired with microcontrollers like Arduino, Raspberry Pi, or ESP8266, this RF pair allows for reliable wireless communication over moderate distances with minimal setup.
Important Notes
-
Use an external antenna (e.g., 17.3 cm wire) for better range and stability.
-
Ensure clear line-of-sight for maximum transmission distance.
-
Avoid interference from other 433 MHz devices nearby.
