Motion Detector (PIR, uWave, etc.)

Intelligent Occupancy Sensing Solutions from Texas Instruments

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 design challenges that effect motion detector systems.

  • TI designs 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
  • TI designs show how to implement low power wireless communication to the motion detector
  • TI’s wide range of wireless communication devices include Wi-Fi®, Bluetooth, Zigbee and other 2.4GHz and Sub-1GHz standards help you design for the Internet of Things (IoT)
  • TI has a broad portfolio of operational amplifiers and comparators for various methods of motion detection, including PIR sensors and ultrasonic sensors
