All electronics designers, at one point or another, needs to transfer information wirelessly. While wires are a great and reliable way to connect devices together, sometimes they are not practical. To ...

Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

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 ...

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 ...

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 ...
