Pololu Digital Distance Sensors

These lidar‑based digital distance sensors provide a compact way to detect objects or measure range using a single microcontroller pin. The pulse‑width output versions encode distance as the duration of a high‑level pulse, matching the timing style of hobby servo signals, while the binary‑output models simply go low when an object is present. Available ranges from a few centimetres up to three metres let you choose the right reach for obstacle avoidance, line‑following robots, or proximity‑triggered mechanisms. Side‑entry connectors simplify wiring in tight enclosures, and the straightforward digital interface ensures reliable integration with most development boards. Consistent performance and low latency make them suited for both rapid prototyping and more permanent automation projects.
