Motion or occupancy detectors are used to detect security threats, save energy by efficient lighting control and trigger other IoT enabled devices. Our integrated circuits and reference designs help you add different technologies (passive infrared sensor (PIR), mmWave radar, microwave, ultrasonic, time-of-flight, etc.) to your system.
Design requirements
- Long battery life of more than 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 versus pet
