Remote device control using Radio Frequency


The project compares the communication of control signals using radio frequency
and Infra Red Rays. The STR is ideal for short-range remote control applications where
cost is a primary concern. The receiver module requires no external RF components
except for the antenna. It generates virtually no emissions, making FCC and ETSI
approvals easy. The super-regenerative design exhibits exceptional sensitivity at a very
low cost. A SAW filte ....etc

EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC MOTOR



The project ‘’EMBEDDED BASED RADIO FREQUENCY SPEED CONTROL OF DC
MOTOR’’ is used to varying Speed of The dc motor. It is need a DC to DC converter
is a Circuit Which converts a source of direct current (DC) from one voltage Level to
Another.
Linear regulators output can only in low in low voltage From the Input.
They are very inefficient if the voltage drop is large and the Current high as they
dissipate as heat, a power equal To the product of the output current and ....etc

The quantum of energy in the universe is constant. Neither can man create energy nor can he destroy it. All that he can do is to discover new source of energy that the natural has provided and make it usable for his needs by new and more efficient ways of conversion.
A solar powered refrigerator using an intermittent ammonia-water absorption system as refrigeration in remote areas where electrical energy is not available is described in this paper.


In my present paper I have made an analysis of feasibility of utilization of solar energy i ....etc

a circuit of a remote control unit which makes use of the radio frequency signals to control various electrical appliances. This remote control unit has 4 channels which can be easily extended to 12. This circuit differs from similar circuits in view of its simplicity and a totally different concept of generating the control signals. Usually remote control circuits make use of infrared light to transmit control signals. Their use is thus limited to a very confined area a ....etc
