RF module does have some limitations which is it can only provide one way data transfer. Extra data can only be sent by transmitter to the receiver but not the other way around. This factor limits ...

These days, 433-MHz RF transmitter/receiver modules are very popular with electronics hobbyists and tinkerers. These cheap short-range radio modules can be used with almost all microcontrollers for a ...

Claiming to provide highly stable operation in a 10% smaller package compared to similar devices, the FMRTF3 transmitter and FMRRF1 receiver modules require no external components. They operate on ...

It consists of two modules, a transmitter and a receiver. The transmitter is a set of lasers, one is visible red for aiming, and the other is infrared for measuring the vibration of a surface.

To test the module, first of all, point any NEC-protocol remote control toward the infrared receiver (infrared eye) of the module and press any key of the remote control handset. If the module is okay ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

Figure 1 shows the transmitter based on the microcontroller PIC16F1619. Pushbuttons PB1 thru PB4 are enabled to control four relays in the receiver module in Figure 2. 2. Here’s the receiver ...

Whether you need a headphone adapter, a Bluetooth receiver for your home-audio setup, or a Bluetooth transmitter for your TV, we’ve tested them and have recommendations. Use this tiny ...

In 100-unit sample quantities, the AFBR-81uVxyZ transmitter module and AFBR-82uVxyZ receiver modules sell for $649 per transmit/receive pair. The AFBR-83PDZ CXP module sells for $749, also in 100 ...
