How to find out the sensor reading speed

Hi I currently have 3 ir obstacle avoidance sensors, how do I determine the reading speed of the three sensors to determine the sensor's performance in terms of reading speed. Sorry I'm still a beginner

Are you asking about the "reaction time" of the IR sensor, or about how long your Arduino program takes to determine if the pin is high or low?

If you can find a data sheet for your sensor, it might indicate reaction time.

The sensor data sheet will tell you how quickly a measurement can be made.

For example the Sharp GP2Y0A21YK0F Analog Distance Sensor takes one reading about every 40 milliseconds.
