What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino? [Brett Killion] did make that combination and wound up with a practical network analyzer. T… ...

Arduino project for receiving and (in the future) transmitting signals using a 433 MHz RF module. Currently, this repository contains code for a 433 MHz signal receiver , which allows reading signals ...

This project establishes a wireless temperature and humidity monitoring system using an Arduino Mega 2560 R3 with a DHT11 sensor and an RF 433MHz transmitter to send data. On the receiving side, an ...

Long-range RC transmitter “I started using Bluetooth devices like the HC-05 modules, but I found that these sometimes randomly disconnected. Since then I’ve been using the NRF24L01 modules ...

Finisar Corporation today introduced the industry's first 3 GHz RF-modulated, wavelength-tunable optical transmitter in a Small-Form Factor module. With its wide RF dynamic range, this transmitter ...

AtmelCorporation (www.atmel.com) has combined an 8-bit AVR flash microcontroller with an RF transmitter in two new devices that target tire pressure monitoring systems.
