433 Mhz RF Transmitter Receiver – Pair

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
