Passive Infrared Sensor (PIR) working with Applications

PIR Sensor. The detected radiations are converted into an electrical charge, which is proportional to the detected level of the radiation. Then this charge is further improved by a built in FET and fed to the output pin of the device which becomes applicable to an external circuit for further triggering and amplification of the alarm PIR sensor range is up to 10 meters at an angle of +15o or -15o.

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

10/01/2016· 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 tried placing plastic wrap or the reflective static free plastic that electronics are shipped in over the end of the tube, these do not seem …
