PIR Motion Sensor Module
HC-SR501 (DSN-FIR800) Human presence sensor detects the presence of a moving human (& large animal) bodies in a wide field of viewing angle. PIR Detectors are commonly used in Security systems and Automation. This module comes with 2 onboard trimpots for adjusting both - the sensitivity and the dwell time- or the amount of time the output stays active since the detection was triggered.. Importantly - this sensor can stay ON while the motion is detected and will not switch itself off at every interval. The module has 3.3v Logic level output and can be used directly with Arduino and similar various MCU development boards and robotics projects.
