Do you have a problem with it? Or did you just provide a tutorial to hook up a PIR sensor to an Arduino?

……it was exceeding even I reduced the sensitivity value….why I don’t know???

That does not sound like a question. I don’t know what you want us to do with this.

Assuming you have a problem and need help: What is the brand and model of the PIR sensor? If you want help with something maybe let’s first locate a datasheet. What sensor value did the Arduino report on the serial monitor. What was it exceeding?

What was it exceeding?

My patience ?
