PROJECT DESCRIPTION

The main intention of this project is to control  speed of a fan wirelessly using a standard TV remote based on a thyristor power control method.

The proposed system uses a microcontroller of the 8051 and a load is controlled by a TRAIC duly interfaced to the microcontroller. A standard TV remote sends infrared coded data to the control board, which is received by an IR sensor (at the receiver end) and interfaced to the microcontroller. 

If any button is pressed on the remote, then it sends an infrared coded data within a specific range. This coded data received is executed by the microcontroller to deliver delayed firing pulses to the thyristor, and then it switches the fan power accordingly the respective speed. Firing angle is displayed on a 7-segment display. In this project, a lamp is provided in place of the fan for demonstration purposes.

The future scope of this project can be enhanced by adding more outputs from the microcontroller feeding relay drivers to switch on/off domestic loads together with the speed control of the fan.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  What is remote AC power control?
A:  Remotely or wirelessly controlling load with the help of a TV remote, this is also be done with Bluetooth. See model no. 329. Follow the link: http://www.edgefxkits.in/remote-induction-motor-control-by-android-application-with-7-segment-display
Q:  Can I use a motor instead of the lamp?
A:  Yes, an AC motor with rating- ΒΌ HP, 230V can be used.
Q:  What is the purpose of 7 segment display?
A:  The 7 segment display shows the button pressed on the TV remote for the delay angle
