Motion detector aids designers in adding different technologies

21-04-2020 | Texas Instruments | Test & Measurement

Motion or occupancy detectors, available from Texas Instruments, are employed to detect security threats, save energy by using efficient lighting control and triggering other IoT enabled devices. These integrated circuits and reference designs assist users when adding different technologies (PIR, mmWave RADAR, ultrasonic, microwave, and ToF, etc.) to a system.

Motion detector designs frequently 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; and ability to accurately detect and classify objects, such as human vs pet.
