PROJECT DESCRIPTION

The project is designed to control the speed of an induction motor such as fans, by using a standard TV remote. In home automation application, convenience of remotely controlling the speed of the fan is achieved.

 A standard TV remote sends coded infrared data to the control board, which is then received by an IR sensor (at the receiver end) interfaced to a microcontroller of 8051 family. Each time a button is pressed it sends a specific coded data in infrared range. This coded data is executed by the microcontroller to deliver delayed firing pulses to the thyristor controlled bridge through optical isolation.

The power to the load connected in series with the thyristor is controlled based on the received signal. Also the firing angle is displayed on a 7-segment display. A lamp load shall be provided in place of a motor whose varying intensity demonstrates the varying power to the motor for speed control. A lamp is provided in place of an induction motor for demonstration purpose.

Further the project can be enhanced by adding more outputs from the microcontroller feeding relay drivers to switch ON/OFF the domestic loads together with the speed control of fan.

Q & A
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
Q:  How can the bulb intensity be varied?
A:  The bulb intensity can be varied by delaying the firing angle of the thyristor.

I decided to buy a kit from Edgefx because I saw the project at a dealer in Lucknow where I came to know about the website but purchased directly from the site because kit is very small with the dealer compared to the website kit.I like the sensor based remote provided in the kit that is able to control the kit with remote from a certain distance.
