AKM Semiconductor’s AK9754AE is an ultra-small, ultra-low power, short-range quantum IR sensor with signal processing circuits and human approach detection algorithms. The IR sensor can detect a human approach and outputs a signal from interrupt pins. An analog-to-digital converter (ADC) provides 16-bits data outputs. The sensor can detect humans by using the human-approach detection algorithm.
