AK9750

AKM’s AK9750 is an ultra-low power and compact infrared-ray (IR) sensor module. It integrates four quantum IR sensors and a signal processing IC. The four IR sensors’ offset and gain variations are calibrated at shipment making system calibration not necessary by users. An integral analog-to-digital converter provides 16-bits data outputs. The AK9750 achieves human detection function easily because it employs a PIR (passive infrared ray) type infrared-ray sensor and includes a field of view limiter as well as an optical filter in order to limit detection area. This device can detect human presence not only in motion but also not in motion because it converts an IR of human body to electrical signal directly.
