IC/Module: AMN11112 Passive Infrared Motion Sensor
AMN11112 is a digital output with 3V operating voltage, standard detection type, and white lens. This passive infrared type motion sensor detects even the slight changes in infrared spectrum that occur as a result of movement by a person or object, different in temperature from the surroundings. The sensor detects temperature differences, and thus the motion of the object. The ultra-compact design makes it ideal for use in miniaturized devices.
Pyroelectric Effect Based Infrared Sensor
The Motion Sensor Board provides movement detection with its sensors quad-type pyroelectric element. This pyroelectric nature of the sensor recognizes temperature variations, which enable detection of even the slightest movement in the infrared spectrum range (10 m). On movement detection, the sensor outputs a logic 1.
