Reference Designs


Motion detectors, or occupancy detectors, have several applications in building automation systems. They sense a person’s movement and presence in a room or zone, and are often used as an input device to building security or lighting control systems. Regardless of the application, there are some common problems that effect motion detector systems. One of these issues is false triggering or false alarms. TI has a broad portfolio of operational amplifiers and comparators for various methods of motion detection, including PIR sensors and ultrasonic sensors.

TI designs also demonstrate ways to achieve long battery life for low power designs, for example, our design showing how to achieve up to 10+ years on a single coin cell battery. In addition, TI designs show how to implement low power wireless communication to the motion detector, effectively preparing it for a place in the connected building internet of things (IoT). TI’s wide range of wireless communication devices include Wi-Fi®, Bluetooth, Zigbee and other 2.4GHz and Sub-1GHz standards.
