IR based Remote control for FAN speed control & 4 LIGHTS on/off

1. Overview
IR Remote control is a combination of Infrared transmitter and Infrared receiver which contains 4 relays and 1 Fan Speed Control through TRIAC, which can be controlled wirelessly. This makes the unit very easy to operate and integrate with existing systems. The remote control operate the corresponding relay on the receiver board, i.e. Light 1 operates relay 1, Light 2 operates relay 2, etc. Relay contact can control any equipment in momentary mode (On till key pressed) or Latch Mode (Toggle on each key press). Each relay has indicator LED showing current status.

The transmitter uses a modulated 40 kHz carrier to transmit data about which button is pressed. This method is used in all IR remote controls as it offers a high degree of noise immunity against interfering light sources. At the receiver end the IR receiver module extracts the data signal from the carrier. This active HIGH output is used to operate a relay via ULN2803 which is an octal transistor array.

Special Feature:

• Memory backup - Memory backup saves last condition of relays if power has gone with FAN speed also.
• Custom Build Remote Control with Sleek match

2. Features

• Transmitter operating range up to 10 meters visible distance
• Compact 3V Battery Operated Transmitter
• Receiver Indicates output status by LED
• Receiver operates from 12V AC (for fan speed) or DC power supply
• Relay contact are brought out as Screw Terminals

3. Applications

• Burglar alarm system
