Smart RF Receiver Module


Decoding and Code Learning Feature

HIB03-PT-433 is an ASK/OOK compaitable super heterodyne receiver module with intelligent code learning and decoding feature. It is a smart hybrid circuit which integrates RF demodulator and data decoder for PT2260, PT2262, PT2240, EV1527 encoders. It is intended to use with 433.92 Mhz ISM band applications.

By incorporating the decoder stage to the RF part, HIB03 smart hybrid reduces the cost of the final project and enhance the code efficiency of application software.

Microcontroller based design. With Code Learning Capability, the module can learn 80 different-coded remote transmitters. No need any hardware for address matching. With automatic data rate detection, no need any hardware for oscilator adjusting.

With directly logical outputs according to transmitter’s encoder data pins, it is nearly a plug and play solution. The only setup is pressing the learning switch to teach the remote control to the module.
