• Easy to use, nice range (using antenna on both), you can send strings (text) from one point to another. If you want to automate your house without pulling cables then this device will help you well
• Wireless Transmitter Modules allow your Arduino to wirelessly comunicate with other arduinos, or with radio frequency (RF) controlled devices that operate in the same frequency (433Mhz in this case)
• They work in pairs, meaning you need both a receiver and a transmitter to comunicate with each other
• Compatible with SparkFun’s 434MHz RF transmitter and RF receiver
• This Radio Transmitter & Receiver pair is perfectly matched to allow you to control items from a distance up to 500 feet wirelessly!
