The PTFS 100Hz Laser Sensor is a compact laser sensor to measure distance, offering a 100 m range with 0.1 m resolution and a 100 Hz update rate. It is powered by 3.3 V DC, uses a 905 nm Class 1 laser, and features UART output. The sensor measures just 43×35×21 mm and weighs approximately 30 g. A low‑frequency version (1–3 Hz) is also available, which extends the measuring range up to 700 m.
