Inventions can help physically-challenged people lead life with fewer difficulties. Mohd Thamrin, Rosman R. and Sarmawi D. S. of UiTM Shah Alam Malaysia studied the use of inexpensive RF transmitters ...

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 ...

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 ...

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 ...

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 ...

RF Digital has released a fully FCC and CE-compliant 2.4GHz ULP wireless module in 15 by 15 by 3mm form factor powered by the nRF24LE1 ultra low power single chip transceiver, from wireless specialist ...

Vayyar’s RF sensors consolidate 72 transmitters and 72 receivers for longer range and a higher quality image. The sensors can see through materials, differentiate between objects and people, and map ...

Thales has developed TopStar Galileo core modules in two standardzed, easy-to-integrate versions. The small-form-factor Galileo OS (Open Service) or PRS (Public Regulated Service) sensors are designed ...

Let’s say you need a way to make a project wireless, but don’t have the scratch for a ZigBee or its ilk. You could use IR, but that has a limited range and can only work within a line of sight of the ...

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 ...
