To gain an understanding of the sensor operation you need the circuit of the sensor. The sensor in the photo has an LED and a phototransistor. It sees changes in the light absorbtion as changes in the photo transistor conduction, which results in a changing voltage output.Hi
I have a sensor kit with a many of sensor. I want to understand each sensor's work, how they work without connecting to microcontroller. I would like to use broadboard and multimeter for testing

Can anyone help me understand working of above sensor
The sensor you show in your first post is not the same as on page 31 of that link. The sensor in your fist post probably doesn't need a microcontroller. Have you switched fields?sensor kit https://aws.robu.in/wp-content/uploads/2017/07/Arduino-37-in-1-Sensors-Kit-1-1.pdf
I think microcontroller will have to be used to test this sensor.so far now I will postpone this plan and I will test other sensor in which microcontroller is not required
You have yet to say which sensor you are using. You show the picture of one and link to a different one that doesn't meet your specification of not using an MCU.I do not have documents or user manual for all sensor. I thought that the given link might useful to understand the sensor, so I had posted that link
