Description
This 433MHz wireless transceiver module set provides a foundational RF link for short-range data transmission and remote control applications. The system employs ASK modulation, a common and simple method for sending digital data over radio waves, making it ideal for beginners and cost-sensitive projects. The transmitter module is designed around a stable SAW resonator, offering a compact, effective solution.
The receiver is an ASK hybrid type with a 1MHz IF frequency, providing good sensitivity (-105 dBm) for reliable data reception. The pair operates on a wide voltage range and consumes minimal current, making it suitable for integration into battery-operated IoT sensor nodes, remote keyless entry systems, and basic home automation setups where complex protocols like Wi-Fi or Bluetooth are unnecessary.
