Grove - PIR Motion Sensor-Low-cost&Easy-to -use motion detector-beginners friendly
A passive infrared sensor is an electronic sensor that measures infrared light radiating from objects in its field of view. They are most often used in PIR-based motion detectors. PIR sensors are commonly used in security alarms and automatic lighting applications.
Features- Easy to use: Grove compatible interface and supports both Arduino and Raspberry Pi platforms
- Flexible detecting: Detecting angles up to 120 degrees, and adjustable detecting distance and holding time
- Small-design: 20mm x 40mm
- Wide application: it is commonly found in appliances and gadgets due to its low-cost, low-power,easy-to-use, and long-life cycle.
PIR Sensor is short for passive infrared sensor, which applies to projects that need to detect human or particle movement in a certain range. It is also known as PIR (motion) sensor or IR sensor.
Technically, PIR is made of a pyroelectric sensor, which is able to detect different levels of infrared radiation.
If the PIR sensor notices the infrared energy, the motion detector is triggered and the sensor outputs HIGH on its SIG pin. The detecting range and response speed can be adjusted by 2 potentiometers soldered on its circuit board, The response speed is from 0.3s - 25s, and max 6 meters of detecting range.
It is commonly found in appliances and gadgets used in homes or businesses because it is small, low-cost, low-power, easy to use, and won't wear out.
