Description

Motion or occupancy detectors are used to detect security threats, save energy by efficient lighting control and triggering other IoT enabled devices. Our integrated circuits and reference designs help you add different technologies (PIR, mmWave RADAR, microwave, ultrasonic, and time-of-flight, etc.) to your system.

Motion detector designs often require:

A long battery life of 10+ years
Extremely low noise analog signal chain for long detection range (10m – 15m)
Low settling time of amplifier stages
False trigger avoidance due to environmental changes
Ability to accurately detect and classify objects, such as human vs. pet
