Designed to be economical, Powercast claims that it has lowered the barrier to entry where RF wireless power can actually become ubiquitous with multiple RF transmitters covering every home. Ubiquity ...

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.

Superheterodyne AM Receiver Circuit. Now, we know the basic functionality working of a Superheterodyne Receiver, let’s take a look at a typical circuit diagram of Superheterodyne Receiver. The below ...

A simplified block diagram, explaining how Digital Electricity technology works, is shown in Figure 1. It first takes an analog electricity input (either AC from the mains or from a wall socket, or DC ...

As shown in block diagram of the project in Fig. 1, there are two distinct parts—transmitter (sensor node) and remote data receiver. The sensor node consists of different sensors, microcontroller, RF ...

The technique makes use of an RF signal generator and analyzer to predominantly focus on calibration and verification of device RF transmitter and receiver performance. This type of testing is ...
