Product Details
This kit is used for one way wireless communication at a frequency of 433MHz and includes a transmitter module and a receiver module. The twig configuration of this kit allows for around 40 meters of transmitting distance indoors, or around 100 meters outside.
Features
- GROVE compatible interface.
- Uses ASK (Amplitude Shift Keying) Modulation.
- One way communication.
Application Ideas
- Remote control
- Remote automation
- Alarm
Usage
The transmitter and receiver modules both rely on a single wire for communication. Though using the UART supplied by the arduino platform can work, it is recommended, instead, to use the VirtualWire library which uses Amplitude Shift Keying for modulation which provides better communication.
Both the transmitter and receiver modules require three wires: Vcc, Ground, and signal. Pin 2 of both parts of the kit are not connected.
