RF Wireless Tx & Rx Module 433Mhz

RF modules are widely used for wireless data transfers and remote control applications. These days, cost of RF modules are very low and are compact in size. Most of these RF modules are operating around 433MHz. Amplitude Shift Keying (ASK) or Frequency Shift Keying (FSK) are mainly used for wireless data transfers.
 

Technical parameters of the transmitter head

• Transmitting power: 10mW
• Transmitting frequency: 433M
• Pinout from left → right: (DATA; VCC; GND)

Receiver module parameters:-

• Operating mode: AM
• Operating voltage: DC5V
• Quiescent Current: 4mA

  here 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.
