    Generally some controllers have ir modulation option. suppose we don't have option with mictrocontrollers , how to generate 33khz pulses and also communication of ir , kindly suggest tx and rx circuit

    If you haven't the ability to use a microcontroller at the transmitter (from the meter), how were you going to generate the data/signal to modulate the IR? Any simple oscillator can be built to run at 33KHz. Placing predictable and meaningful modulation on the signal is a larger problem.
