About the Ir sensor strobe PCB

Ir sensor strobe is an open source PCB design by bburan, published on GitHub. It is a 2-layer board measuring 37.5 × 43.5 mm, with 27 components from 17 distinct parts.

Other key parts include the TLC555CP. By type, the board carries 12 resistors, 8 connectors, 5 capacitors, 1 IC and 1 transistor.

It belongs with the sensors designs in this gallery.

From the project

A small four‑channel infrared emitter/detector board. Four IR LEDs (OP140) are driven as a single strobed array; four phototransistors (OP550) act as independent detectors, each presenting an analog output to a downstream acquisition system.

The strobe carrier can come from either an on‑board ~500 Hz oscillator or an external control signal, selected by a jumper at J1. The optoelectronics mount remotely and connect through headers. The board is all through‑hole and is intended to be hand‑soldered.
