PIR SENZOR WIKIPEDIA

detector de mișcare -

Senzorul piroelectric (senzor PIR, P yroelectric I nfra r senzor ed) este cel mai frecvent utilizat tip de detector de mișcare. Reacționează la mici modificări de temperatură, de exemplu atunci când o persoană trece pe lângă senzor. Detectoarele de mișcare care utilizează microunde reacționează optim atunci când se schimbă distanța până la senzor. Senzorii cu ultrasunete sunt ...

Passive infrared sensor - WikiMili, The Best Wikipedia Reader

A PIR sensor can detect changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor. [2] When an object, such as a person, passes in front of the background, such as a wall, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature ...

Pyroelectric sensor -

Commercially available PIR sensors for motion detectors consist of two adjacent sensor elements with dimensions of 1 mm to 2 mm. The absorption coating used for this has the highest sensitivity in the middle infrared at wavelengths in the range from 5 µm to 14 µm. The sensors are usually housed in a hermetically sealed transistor housing, such as the TO-5 design, together with a preamplifier ...

PIR Sensor Circuit and Working with Applications

PIR sensor consists of three pins, ground, signal, and power at the side or bottom. Generally, the PIR sensor power is up to 5V, but, the large size PIR modules operate a relay instead of direct output. It is very simple and easy to interface the sensor with a microcontroller. The output of the PIR is (usually digital output) either low or high. PIR Sensor Circuit PIR Sensor Circuit. The PIR ...

RCWL-0516 Microwave Motion Sensor - Let's Control It

Similiar to PIR sensors a microwave sensor can be used to detect moving persons. The sensor works based on the same function as a radar, just smaller. Difference between PIR and Microwave Sensor. The PIR uses infrared light to detect a moving temperature difference. Infrared light stops at the next wall so a PIR is limited to the room. A microwave sensor uses very high frequency radio waves ...

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

2014-01-28· 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 piece of ...
