INFRATRONIC - long range PIR - SICURIT

· Long-range Passive Infrared Detector (PIR) has been developed for detection of intruders up to 150 meters. Can be used when the installation of traditional active infrared beams is difficult or impossible. Moreover the area protected cannot be identified by an intruder due to the passive operation of the unit. OPERATION. Infratronic is a passive device designed to detect any intruder by his ...

VERY Short-range PIR Sensor | element14 | Sensors

· The PIR sensor on the outside of the closet (to turn the light on) has to be VERY short-range so that it doesn't pick up any of the usual motion in my daughter's bedroom -- again, just long enough (and ONLY long enough) to pick up a waive of the hand in front of the sensor (3-4 inches). I am going to wire the OUTSIDE PIR sensor so that a waive of the hand will turn the light ON or OFF …

• PIR_SHORT_TERM_FILTER_RANGE – This parameter sets the length of the short term filter. Changes to this parameter need to be done carefully while also considering the PIR_LONG_TERM_FILTER_RANGE and PIR_DETECTION_THRESHOLD parameters. Changes can affect the effective range of the system and increase power consumption. AN3641 Demo Operation

PIR Motion Sensor With 0-1cm Sensing Range | All About ...

· There are PIR (Passive Infrared Detector) motion sensors, which typically have a range of several feet, and are built as a single unit to detect the IR from (typically) a warm-bodied animal. Then, there are IR emitter/detector pairs which are active devices and employ a beam break mode of operation; sometimes these can be used up to a few feet apart, but often they are used with the emitter and the …

PIR sensor Small Range - Sensors - Arduino Forum

· When my hand moves in front of a sensor (range about 15 cm or less) the LED if off. When the hand is further away, (more than 15cm) the sensor can not respond to this. An ultrasonic 'ping' sensor might be more suited to this. Beacause it actually measures distance, unlike a PIR sensor, you'd get bettter results. But a ping sensor doesn't work at distances smaller than several cm. You could …

Can you limit the range of a PIR sensor? - Emergency ...

· To do this they use a pair of sensors wired as opposite inputs to a differential amplifier so that PIR measurements cancel each other thus the average temperature of the field of view is removed from the electrical signal. The field of view is the result of the radiation going through fresnel lenses and hitting one of the two sensors. Thus the device is only seeing what comes from various beams.

Overview | PIR Motion Sensor | Adafruit Learning System

· PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors…
