Features:

Further integrated features of the ProxFusion® IC’s include capacitive proximity/touch sensing, inductive sensing, ambient light measurement, temperature and Hall-effect sensing. These features can be combined with the PIR sensors for energy efficient lighting, room occupation & security applications.

Typical uses:

Room occupancy detection
Lighting applications
Alarm systems
Smart Home systems
Movement detection
Under Cabinet Lighting (UCL)
Battery powered PIR sensor solutions

Advantages over conventional PIR sensing circuitry:

Raw data output for smart DSP algorithm
Adjustable sensitivity (gain) via I2C
Less components required
Smaller PCB and less PCB layers required
Multiple features (PIR/tamper detection/magnetic switch/ALS) on one IC
Two PIR elements measured by one IC
Low power consumption – IQS62x current less than 6uA (fs-10Hz)
Less MCU processing required
Smart tamper detection
SNR: 38dB
