The Adafruit PIR has a trimpot on the back for adjusting sensitivity. PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. The range is from about seconds . You can in fact build your own motion sensor without spending too much.
Motion sensors can be setup using ultrasonic transceivers, video . Arduino Micro program to sample an analog passive infrared motion sensor and display the on a graph.
I was trying to figure out the lux. The passive infrared sensor is a. Using the power of the sun, light any dark area and add extra security with the Sunforce Solar Motion LED. There is no way to modify it in software or in the electronics. I would adjust the values of Rand Rto reduce the gain and make the.
