Module with IR obstacle sensor

A miniature lidar proximity sensor that detects objects up to 10 cm away, regardless of color, transparency, or lighting. It generates a digital signal (0 V on detection), operates in the 3-5.5 V range, draws only 30 mA, and supports sleep mode via the ENABLE pin. Ideal for robotics, automation, and contactless interfaces, it offers a fast response time (142 Hz), switching hysteresis, and a compact housing with an indicator LED. Pololu 5462
