No, PIR (Passive Infrared) sensors and motion sensors are not exactly the same. PIR sensors are a type of motion sensor that detects movement by sensing changes in infrared radiation, while "motion sensor" is a broader term that can include various technologies such as ultrasonic, microwave, and camera-based sensors. Therefore, all PIR sensors are motion sensors, but not all motion sensors are PIR.
