The Grove - 433MHz Simple RF Link Kit from Seeed Studio consists of one transmitter and one receiver and is useful for remote control projects that don't require two-way communication. To attach one of these modules to a microcontroller simply plug into a Grove base board and use a serial transmit or receive signal, making it very light in terms of GPIO pins.
- Frequency: 433Mhz
- Modulation: ASK
- Receiver data output: High - 1/2 Vcc, Low - 0.7v
- Transmitting range (at 5V): 40m indoor, and 100m in open air
