AK9754

[AK9754] AK9754 Ultra-small IR Sensor IC with I2C I/F 1. General Description The AK9754 is an ultra-low power and ultra-small quantum infrared-ray (IR) sensor module with signal processing circuits and Human Approach Detection algorithm. It can detect a human approach and outputs a signal from interrupt pins. An integral analog-to-digital converter provides 16-bits data outputs. Human detection can be easily realized by using built-in Human Approach Detection algorithm. The AK9754 is suitable for human sensing application. 2.
