Enhanced PIR Sensing

The IQS62x ProxFusion® IC’s can be configured as a multi-functional Pyroelectric Infrared Radial (PIR) sensor. This configuration can be used for applications such as energy efficient occupancy detection and other applications by means of movement detection.

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
