It is often required to switch electrical appliances from a distance without being a direct line of sight between the transmitter and receiver. As you may well know, an RF based wireless remote ...

Members can download this article in PDF format. 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 ...

We’ve seen no shortage of projects that use the ESP8266 or ESP32 to add “smart” features to existing home appliances, often by pairing the microcontroller with a radio or IR transmitter. If your ...

This project pairs a set of 8-bit microcontrollers with a 433-MHz industrial, scientific and medical (ISM) band transmitter/receiver. The FS1000A RF transmitter has a range of up to 200 m; the ...

The FM receiver module is based on the TEA5767 [1, 2] chip. It is a well-known module that could be controlled via the I2C bus. It covers the FM frequency range from 76MHz to 108MHz. At the output, it ...

Wireless is easier today than ever, with many standards to choose from. But you don’t need anything elaborate if you simply want to cut the cord. A few years back, [Roman Black] experimented with the ...

Powercast’s Ubiquity transmitter and receiver modules allow device manufacturers to build low-cost wireless charging and two-way communication into everything from electric toothbrushes to home ...

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 ...

LOUISVILLE, Colo., May 30, 2019 – Inovonics, an industry leader in high-performance wireless sensor networks for life safety applications, announces the release of its new EH4104R single zone fire RF ...
