Introduction :
Wireless RF Kit 433 Mhz (Transmitter+Receiver) module comprises an RF Transmitter and an RF Receiver.
The transmitter/receiver (Tx/Rx) pair operates at a frequency of 433 MHz.
An RF transmitter receives serial data and transmits it wirelessly through RF through its antenna connected at pin4.
The transmission occurs at the rate of 1Kbps – 10Kbps. The transmitted data is received by an RF receiver operating at the same frequency as that of the transmitter.
This low-cost RF transmitter can be used to transmit signals up to 50-100 meters (the antenna design, working environment, and supply voltage will seriously impact the effective distance).
It’s good for a short distance, battery power device development. 433 MHz is the operating frequency for transmitter and receiver pair.
Features :
- Operating Voltage : 3V – 12V
- Operating Frequency : 433.92MHz, 315Mhz.
- Operating Current : 20 – 28 mA.
- Easy to integrate (V+, GND, and Data)
- The device in deep sleep mode when Data pin is grounded
- Very small dimension.
