This pair consists of an RF transmitter and receiver. These can be interfaced with Encoder and Decoder ICs. For better accuracy, antenna should be used at transmitter and receiver ends.
- Frequency: 433 MHz.
- Modulation: ASK
- Receiver data output: High – 1/2 Vcc, Low – 0.7v
- Transmitor input voltage: 3-12V (high voltage = more transmitting power)
- Receiver Input Voltage : 3.3-6V (high voltage = more receiving power)
- Transmitting range (work at 5V): 40m indoor, and 100m in open air
