These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet… ...

Using an EH4104R single zone fire RF receiver with relays and an EH1115EOL single input fire RF transmitter, a wireless link can be easily created for any fire switch with standard contacts.

Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected.

Atmel’s ATA8520D is a transceiver IC for 868MHz Sigfox proprietary networks, intended to be used for IoT and machine-to-machine comms with the Sigfox protocol. It has an RF front end for up and ...

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.
