Remote-Controlled Smartfan Using AT89C | Full Electronics Project
The circuit can be operated up to a distance of meter depending on the remote used. The circuit works tsop1378 regulated 5V, which is derived from X1 and regulated by IC1.
The IR receiver module operates at this frequency. It is used to control relay RL2. The relay triggers IC2, which is wired in a bistable mode to control the home appliance connected at the contacts of relay RL1.
Threshold tsop138 trigger input pins 6 and 2 of IC2 are held at one-half of the power supply voltage 5V by resistors R2 and R3. When output pin 3 of IC2 is high, capacitor C4 charges through resistor R4, and discharges when the output pin 3 is low. When switch S1 is pressed, capacitor C4 voltage is applied to pins 2 and 6 of IC2, which causes the output of IC2 to change from low to high, or high to low.
Remote Controlled Switch for Appliance
When switch S1 is released capacitor C4 charges or discharges to the original level at the output pin 3 of IC2. The working of the circuit is simple. Initially, when there are no IR rays falling on the IR receiver module, its output remains high. Transistor T2 is in cut-off condition. Relay RL2 does not energies and hence IC2 does not toggle.
As a result home appliance connected at the contacts of relay RL1 remains switched off.
Relay RL2 energizes and triggers IC2. Output of IC2 goes high and relay RL1 energizes to switch on the appliance.

Once relay RL1 is energized it remains in ird1 state. So the appliance which is connected at the contacts of relay RL1 remains switched on. Now when you press any remote key the second time, relay RL2 energizes and re-triggers IC2. Output of IC2 goes low and relay RL1 de-energizes to switch off the appliance. Once relay RL1 de-energizes it remains in that state. So the home appliance remains off. Assemble the circuit on a general purpose PCB and enclose in a suitable cabinet.
Place transformer inside the cabinet and mains power cord at the back of the cabinet. You are commenting using your WordPress.
