AMN11112 sensor detects movement as changes in infrared spectrum Plastic cap features miniature lenses which boost sensor precision Range up to 2 meters Compact size ideal for miniature devices Compatible with both 3.3V and 5V systems The Motion Sensor Board features an AMN11112 passive infrared motion sensor used to detect changes in infrared rays. This sensor is ideal for small-movement detection, thanks to its quad-type pyroelectric element. When a movement is detected, the sensor outputs a logic 1. This board can connect to standard prototyping boards. The pin pads come unpopulated, so you are free to determine how to connect it to your system. Male pin headers are included that you can solder on. Motion Sensor Board Resources
