The IR object detection module is quiet easy to make. This circuit below is a low cost / low range infrared object detection module that you can easily make at home using IR sensors.

We will use a photodiode and IR LED to make a simple circuit. IR led looks like a regular LED that you usually see in Television Remote controls.
I found a small kit for infrared IR sensor circuit and sharing this here.
For now I have added a regular LED to glow when something is detected , you can replace it with a buzzer or something else the way you wish.

The Main concept is simple , the IR led keeps transmitting IR infrared rays up to some range (there is a potentiometer also in the design with the help of which you can alter the range). When some object comes in the IR infrared range, the IR waves hits the object and comes back at some angle, Photo diode detects that IR  rays and hence works as a sensor.

Requirements
 
1  -IR  LED
1 - PR (photodiode)
1 - 1k resistance
1 - 220E resistance
1- 6k8 resistance
1 - 10k potentiometer

Circuit diagram

For now in this circuit a LED is glowing as an example , You can use it the way you wish, You can use it to run some DC motors and make a simple robot. Or the logic 1 can be used to do complex operation with interface to some microcontroller for some complex projects.

Use the way you want it.
