Description

This is a PIR (passive infrared motion) sensor designed to work with Arduino and Raspberry Pi. It allows you to sense motion, it is commonly used to detect whether a human has moved in or out of the sensor’s 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.

This PIR (Motion) Sensor can detect infrared signals from the human body or other animals and triggers movement. So it can be applied to a variety of scenarios that require motion detection. Conventional pyroelectric infrared sensors require body pyroelectric infrared detectors, integrated chipsets, complex peripheral circuits. So the size is slightly big, the circuit is complex, and reliability is slightly lower. We bring this new pyroelectric infrared motion sensor which is specially designed for your Arduino projects, an integrated digital body pyroelectric and infrared sensor, with small size, high reliability, low power consumption, and simple peripheral circuit. Very simple to use in any project.

Applications:

Moving human detection.
Occupancy detection.
Security systems.

Features:

Low power consumption
Compact size
Cost-effective
Adjustable sensitivity
