How PIRs Work | PIR Motion Sensor | Adafruit Learning System

20140128· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can ''see'' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When ...

ESP32 Interrupts and Timers with PIR Sensor using Arduino IDE

Timers using Arduino IDE. In our PIR motion sensor project, we want the LED to stay ON for a set number of seconds whenever motion is detected and turn OFF after the time ends. To do that, we will use the millis() function which will act as a timer. Using the delay(ms) function is also an option but this function takes in the time in milliseconds as a parameter inside it which denotes the time ...

Problem getting PIR sensor working using interrupts ...

20210506· However I would like to execute some code when the PIR detects motion and polling the value of the sensor in my the loop is not the best option for me since I want to have delays (few seconds) in the loop and this will cause that not all the motions detected by the sensors are handled by the arduino. So it seems that using interrupts is the way to go and I tried but I got some results I was ...
