Abstract: This paper presents the design of a wireless hand switch of X-Ray machine using RF Module. With the objective to avoid unnecessary exposure of radiation, a low cost RF Module is proposed. This method uses RF transmitter and RF receiver modules which are operating at 434 MHz along with encoder IC M145026 and decoder M145027 with the passive components.

The goal of a theoretical framework. After refining your problem statement and research question(s), you have to explore what theories, ideas and models other researchers have already developed. By presenting this information, you frame your research and justify your overall approach.
Greenhouses in the growth of the crops will often because of unfavorable environment not good growth, in order to be able to effectively control the temperature inside the greenhouse greenhouses, humidity, light intensity, make inside the greenhouse crop growth environment to fulfill the requirements of the best. This system by using HOLTEK series single-chip microcomputer as the control.
The wireless remote is a 434 RF module and the robot is driven on DC motors controlled by an L293D motor driver IC. Typically, 434 RF modules have a range of 50-60 metre but can be extended up to 300-350 metre. So, after extending the operational range of RF module, the RC robot will have an impressive distance to wander around.
Wireless and RF With the rapid evolution of wireless technologies and the complexity of new designs, you need a partner who understands the intricacies of RF testing. Tektronix delivers the expertise, as well as the signal generation and analysis capabilities required to overcome the most challenging RF, wireless and microwave design challenges with total confidence.
