The RF Receiver circuit can be powered from a standard 5VDC supply. Just as for the RF Transmiitter, the aerial (17 cm for 433.92 MHz) has to be mounted as close as possible to the RF IN (ANT) pin of ...

Spark transmitter circuit diagram. Compared with the primitive transmitter, our receiver is a more up to date design realised in ‘all solid-state’ electronics. A telescopic antenna picks up the ...

Conceptually the circuit there is simple, consisting of the ultrasonic receiver, followed by a transistor amplifier for the modulated wave, then a diode for demodulation, another transistor ...

This circuit uses the EUSART (Enhanced Universal Synchronous Asynchronous Receiver Transmitter) modules embedded in two PIC microcontrollers 16F1619 and 16F1614. The communication is full-duplex ...

The Inovonics EH1115EOL EchoStream single input fire RF transmitter can be used with any standard contact or sensor. A 2.21K ohm end of line resistor is included with the EH1115EOL, and is ...

One of the great things about the Hackaday community is how quickly you find out what you don’t know. That’s not a bad thing, of course; after all, everyone is here to get smarter, right?

The DA4100 RF-Transmit integrated circuit (IC) is a simplified implementation of Energous' WattUp wireless power transmission system, according to Energous and Dialog Semiconductor.

The transmitter-side inductor and receiver-side inductor used in the matching circuit are configured in a concentric arrangement, and their mutual induction is employed to reduce signal loss and ...

Impedance matching to an antenna in a receiver or transmitter is an essential process. Some loads are constant; thus, a single fixed Z-matching circuit can be used.
