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

For reasons that will be apparent soon, we would like to make the PIR lenses small and thin and moldable from cheap plastic, even though it may add distortion. For this reason the sensors are actually Fresnel lenses (see image below). OK, so now we have a much larger range. However, remember that we actually have two sensors, and more importantly we dont want two really big sensing-area ...

PIR Motion Sensor - Adafruit Industries

· Lenses 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. In the diagram up top, the lens is just a ...

· Fig 2: PIR sensor hooked up to an LED to indicate operation. Note that we removed the lens assembly in the second image. What Does PIR Mean? A passive infrared (PIR) sensor recognizes infrared light emitted from nearby objects. You may assume that “passive” IR sensors mean these devices are less complicated than their active counterparts, but you’d be mistaken. A passive IR …

PIR through frosted plastic? - Sensors - Arduino Forum

· There is another problem: A PIR lens consists of a bunch of fresnel lenses. So sometimes your body heat is focused on the detector, sometimes it is not. So as you move across the field, the heat it picks up goes in and out of view. This is how it detects a warm body. So you cannot use a cover that is translucent to IR. It must be clear for IR ...

How do I replace or repair a motion sensor PIR lens?

The PIR lens/translucent cover for my motion sensor for my outdoor light kit broke. Crumbled to the touch after about a year outside despite being made for outdoors. The sensor is now way too sensitive without it, but the sensor does still work. Is it possible to replace this PIR lens, or do I have to throw the baby out with the bathwater and replace the whole sensor piece? I am not asking ...

· This PIR sensor’s domed lens is made up of Fresnel lenses, Fresnel lenses were designed to save on weight, space, and material while achieving the same qualities of a larger and denser lens. A normal lens is a solid piece of glass forming a continuous convex arc. That glass can be heavy and uses a lot of material, with a fresnel lens the curvature is broken down into slices, and …

using PIR sensor without lens? | Forum for Electronics

· Instead of a lens you an use a grid. Use a dielectric like Teflon to make a grid. Lens or grid are used to modulate the input temperature due to an object moving across the field of view. Only these changes are detected and amplified in the sensor circuit. A PIR sensor can detect the presence of an object but its response is unstable due to 1/f ...
