Understanding Arduino and PIR Infrared Sensors

PIR sensor, which stands for Passive Infrared Sensors, is an electronic component used to detect the infrared radiation emitted by the human body. It senses the presence of a person by detecting the infrared radiation in the surrounding environment, and is commonly used as a motion detector in the security field. Working Principle of PIR … Read more

Arduino Example - PIR Motion Sensor

PIR Motion Sensor The PIR motion sensor, also known as a human infrared sensor, is widely used in fields such as anti-theft alarms, visitor notifications, and non-contact switches. Piezoelectric ceramic dielectrics can maintain a polarized state after polarization, known as spontaneous polarization. Spontaneous polarization decreases as temperature increases and drops to zero at the Curie … Read more
