AK9752

[AK9752] 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. 2.
