arduino - Reducing the sensitivity of a PIR sensor ...

10/01/2016· I am using them with an Arduino Mega 2560 or an Arduino Uno. I have tried placing various objects / films in front of the sensor. Running the sensor through a tube (cardboard or PVC) seems to effectively reduce the sensor to a very narrow beam of detection, however I also need to reduce the overall range, as even with through the tube the sensor fires off at 15-20 feet away. I have …

Arduino lesson – PIR Motion Sensor «

Connect OUT to digital pin 2 on Arduino board. Connect GND with GND on Arduino. You can adjust the sensor sensitivity and delay time via two variable resistors located at the bottom of the sensor board. Once the sensor detects any motion, Arduino will send a message via the serial port to say that a motion is detected.

arduino - PIR sensor always gives HIGH - Electrical ...

04/03/2016· But when I test the output of the PIR , it gives always HIGH . I rotate sensitivity adjustment and time delay adjustment randomly to see any changes occur. I even cover the sensor with cloth so that It get's no infrared . still it gives high. I changed my sensor and bought a new one. This shows the same problem too. arduino code :

Graphical Programming Tutorial for Arduino – PIR Motion Sensor

13/03/2019· Graphical Programming Tutorial for Arduino – PIR Motion Sensor. Introduction. A passive infrared sensor (PIR Motion sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. So, it can detect motion based on changes in infrared light in the environment.
