Stemedu HC-SR501 PIR Sensor Infrared IR Body Motion Module for Arduino Raspberry Pi(Pack of 5pcs)
Stemedu HC-SR501 PIR Sensor Infrared IR Body Motion Module for Arduino Raspberry Pi(Pack of 5pcs)
What is it? This is HC-SR501 Human Body Pyroelectricity Infrared PIR Motion Detector Sensor Module. The human body sensor lighting industrial automation and control, etc.Ideal for Arduino, Raspberry Pi, PIC and more. As per the HC-SR501 data sheet, stops detecting ("detection range is shorter") as temperature approaches 30 degrees celsius (approximately 90 degrees fahrenheit). These units have the through-holes to add a thermistor to improve high temperature performance, if one has a thermistor to add. Easy to set up. Pins fit well into female Dupont wires for prototyping.

Especially suitable for enterprises, hotels, shopping malls, warehouses and family aisles, corridors and other sensitive Sense of region, or for the security zone automatic lighting, lighting and alarm systems. Also, it can work with Arduino or Raspberry Pi projects. Read more Q&A and comment answers What is the signal output polarity? Positive input and output, negative is common. 3 wire connection. Hello, can I use these sensors to connect lamps at home? Yes, you can Why the PIR sensors HC-SR501 don't work? (output stuck high). Please adjust the sensitivity and timing of the sensor, and put it in a box so that it will not detect you all the time. These PIR sensors are the cheapest motion sensor on the market, they are rather simple, limited, and have drawbacks, if you need more precise and reliable sensor we have millimeter wave sensors based on DSP and Baseband SoC. 5PCS HC-SR501 Human Body Pyroelectricity Infrared PIR Motion Detector 3PCS HC-SR501 Human Body Pyroelectricity Infrared PIR Motion Detector HC-SR312 AM312 PIR Motion Sensor HC-SR505 Human Body Pyroelectricity Infrared PIR Motion Detector Sensor Module 5PCS RCWL-0516 Motion Detection Sensor DC 0-25V Voltage Tester Sensor Model HC-SR501 HC-SR501 HC-SR312 HC-SR505 RCWL-0516 package 5PCS 3PCS 5PCS 5PCS 5PCS 5PCS
