A few years back, [Roman Black] experimented with the cheap RF modules you can find on auction sites and from surplus electronics vendors for only a few dollars, and wrote up his findings.

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.

[Ray] wanted to use a microcontroller to send signals to some wireless power outlets. Instead of tapping into the buttons on the remote control he is using an RF board to mimic the signals. There a… ...

These fully integrated modules are suitable for use in telecommunications, test instrumentation, electronic warfare, aerospace, and radar applications. ADI can also perform additional levels of ...

Murata’s millimeter-wave RF modules use an independently developed LTCC* that realizes stable communications quality in the millimeter-wave band and features both high heat and moisture resistance.

Before this project, much of Pepco’s transactions were recorded on paper and the inventory items were hand-labeled. The project will automate the data capture process, and use RF barcode technology to ...

In this design idea, you will learn how to interface two PIC microcontrollers using a wireless 433-MHz RF transmitter/receiver pair to control up to six relays and monitor two analog signals. The ...
