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 ...

In that case, I learnt how to use an Arduino to transmit data using the nRF24L01 module. Afterwards, a potentiometer attached to the transmitter was used to control a servo motor and BLDC. I then ...

This project demonstrates wireless data transmission using a Raspberry Pi Pico (transmitter) and Arduino Uno (receiver) over low-cost 433 MHz RF modules. Messages are encoded bit-by-bit on the Pico in ...

Most consumer remote controls operate using infrared light. This works well assuming the piece of equipment has a line of sight to the remote. But if you have, say a receiver in a cabinet or closet… ...

The RF transmitter and receiver units are the two main components of the system. In this configuration, RF signals including information on the speed limit are broadcast by the transmitter unit, which ...

Using an EH4104R single zone fire RF receiver with relays and an EH1115EOL single input fire RF transmitter, a wireless link can be easily created for any fire switch with standard contacts.

Atmel Corporation has combined an 8-bit AVR flash microcontroller with an RF transmitter in two new devices that target tire pressure monitoring systems.

Targeted for the smart home, this design leverages two PIC MCUs that use a wireless RF transmitter/receiver to control up to six relays and monitor two analog signals.
