can i use this sensor to turn ON  the A/C ?

If A/C = air conditioning, then no?

You either need a high current isolated relay to switch the mains, or else build something that can emulate the remote control, or something that can fool the A/C temperature sensor into thinking that the air temperature is above some threshold.

No.

my Air condition has IR REMOTE to turn it on , so this sensor will not do the same job as the remote can do to turn the a/c on ?

Do you want the A/C to turn on when an obstacle is detected?
If so, then you can use the sensor as an input to an Arduino. You then write a program that runs on the Arduino and sends data to a separate IR LED that emulates your remote control.

Correct. That module will not turn on an air conditioner. It is an obstacle avoidance sensor.

This sensor canot send IR signals as the remote ? If no . Tell me what shoult i buy to send IR signal as the remote control

An Arduino, an IR LED and a 220 Ohm resistor can be  used to send commands to an IR receiver, but you need to know what commands to send.

Google "arduino IR sender" for lots of information.

The sensor in the image above it dont have ir led ?

Yes, the sensor does have an IR LED, but it is connected to circuitry that makes it useless for controlling an A/C unit.

Please calm dawn and relax can i know why it wil be useless ?

The IR Infrared Obstacle Avoidance Sensor board doesn't have a signal input pin to modulate the IR LED intensity.
