AK9750 Human Detection IR Sensor Module

AKM Semiconductor offers its AK9750 human detection IR sensor module which integrates four IR sensors and signal processing with I²C

Image of AKM Semiconductor's AK9750 Human Detection IR SensorAKM’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.

The AK9750 employs an ultra-small quantum-type InSb photodiode based on AKM’s Hall effect element process technology. The photodiode acts as an IR sensor element that can detect IR in high sensitivity and fast response situations. Since center points of four sensor covering areas are different with the field of view limiter, four IR sensor elements can detect space distribution of a heat source.

The AK9750 has an operating voltage from 1.71 V to 3.63 V. It has an integrated temperature sensor that will detect from -10°C to 60°C all in a 10-pin SON package.
