AK9752
Ultra-small IR Sensor IC with I2C I/F
1. General Description
The AK9752 is a very low power and ultra-small infrared-ray (IR) sensor module. It is composed of a
quantum IR sensor and an integrated circuit (IC) for signal processing. The IR sensor’s offset variation is
calibrated at shipment. An integral analog-to-digital converter provides 16-bits data outputs. The AK9752
is applied for detecting human presence.
