Pyroelectric infrared (PIR) sensors are much promising for device-free localization (DFL) due to their advantages of lower cost, low power consumption, and privacy protection. Most PIR-based ...

This paper presents an integrated ultra-low power (ULP) analog front-end (AFE) for motion sensing applications with off-the-shelf passive infrared (PIR) sensors. Existing PIR-sensor-based motion ...

PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...
