PIR repair | DIYnot Forums

· 14. Thanks Received: 0. Location: Suffolk. Country: Hi, The plastic lens on a PIR for an external light became brittle and crumbled into pieces. I did a neat repair using some plastic from a plastic squash bottle. It looks like new, but the sensor now barely detects motion unless it is within an inch of the sensor.

Insight - Learn the Working of a Motion Sensor or PIR Sensor

Beneath the Fresnel lens array is the PIR sensor which is firmly placed in the plastic moldings. Placement of the sensor is crucial as it supposed to receive maximum amount of infrared radiation that comes from the lens array. It is hence placed in the center of the moldings where maximum radiation is converged to drop on. IR Filter & TO5 Metal Can. Fig. 6: Infrared Filter of Sensor. Fig. 6 ...

Advanced Motion Detector Using PIR Sensors Reference ...

Motion detectors containing one PIR sensor, a Fresnel lens with a cone-type beam, and a binary output are very efficient for detecting any type of motion, including a human or pet. However, imagine a customer application based on this type of motion detector that sends a notification and switches on a light when any motion is detected. It could be very annoying to receive notifications and on ...

PIR Motion Sensor Tutorial : 8 Steps (with Pictures ...

PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.
