WK141 Radio Frequency Based Remote Industrial Appliances Control System Controlling industrial / home appliances is a very interesting and useful 5555 212 project. This project is designed to control up to four electrical appliances. This project used popular RF encoder and decoder IC’s. 6695, 888 Four Switches are connected to the RF Encoder. This encoded data is transmitted through a RF transmitter module. In the receiver side, the RF 6363, 6625 receiver module receives the encoded data and decodes using an RF Decoder. This decoded output data is given to transistor drivers. Relays are driven using these transistor drivers. Up to 7A load can be connected to these loads. h: 040 – 6464 In this project 433 MHz RF transmitter and receiver modules are used. These are ideal for remote control applications where low cost and longer range is required. The ts.com P transmitter operates from a1.5-12V supply, making it ideal for battery-powered applications. The transmitter employs a SAW-stabilized oscillator, ensuring accurate frequency control for best range performance. The manufacturing-friendly SIP style package and low-cost make the STT-433 suitable for high volume applications. www.WineYardProjec This project uses regulated 5V, 750mA power supply. 7805 three terminal voltage regulator is used for voltage regulation.
