433MHZ FS1000A RF Wireless Transmitter and Receiver Module

This is FS1000A 433mHz Tx RF Radio Module. This RF 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.

Transmitter 433Mhz:

• Working voltage: 3 – 12V fo max. power use 12V power
• Working current: max Less than 40mA max , and min 9mA
• Resonance mode: (SAW)
• Modulation mode: ASK
• Working frequency: 433MHz
• Transmission power: 25mW (433MHz at 12V)
• Frequency error: +150kHz (max)
• Velocity : less than 10Kbps
• Range: up to 90m in open area
• Size: 21 x 19mm

Receiver 433Mhz:

• Working voltage: 5.0VDC +0.5V
• Working current:≤5.5mA max
• Working method: OOK/ASK
• Working frequency: 433MHz
• Bandwidth: 2MHz
• Sensitivity: excel –100dBm (50Ω)
• Transmitting velocity: 9.6Kbps
• Size 13 x 33mm

Pin Configuration:

Here is a circuit example for interfacing RF module using HT12E/D encoder decoder pair. The circuit attached here can be used to transfer data using the RF module. As I have explained earlier RF module mentioned here is having a single channel. So we can use only serial data transfers. This example uses HT12E/D encoder-decoder pair for converting the parallel data to serial and back.
