Both the HT12E encoder and HT12D decoder IC are hardwired to have address of 0x00. The antennas of height 17.25 cm are connected to the receiver and transmitter sections in addition to the basic setup. The circuit connections are made as specified by the datasheets of the RF module and the encoder and decoder ICs. 1: Block Diagram of RF Transmitter and Receiver Circuit Connections This project is a demonstration of increasing operational range of RF module by increasing the transmission power after the antennas of standard size as according to the antenna theory are already attached to the transmitter and receiver sections. The range of the RF module can be further increased by increasing the transmission power of the antennas. Learn about the sole effect of attaching antenna of standard size on the operational range of RF module. The operational range of the RF module can be increased manifold by attaching external antennas to the RF transmitter and receiver. The typical operational range of 434 MHz RF modules is between 50 metre to 80 metre. Learn about the RF transmission and basic setup of the RF transmitter and receiver modules. These modules are capable of transmitting 4-bit data at once at a data rate of 1Kbps to 10 Kbps. The 434 MHz RF module is the most commonly used module available in the markets. These modules are used for wireless data transmission and for implementing remote control systems. They are also used in large number of consumer electronics products. RF Modules are extensively used by the electronics hobbyists.
