## Summary description

Compact infrared reflective sensor ATSTAROJOŠS, 1‑channel module powered by 3.3–5VDC, dimensions 31×15 mm. Designed to detect reflected infrared light for object presence, edge or line detection, and simple proximity sensing. Suitable for microcontroller projects, robotics and automation where a small, low‑voltage reflective sensor is required.

## Long description

Compact infrared reflective sensor ATSTAROJOŠS is a 1‑channel module designed to detect reflected infrared light. Operating from 3.3–5VDC and measuring 31×15 mm, the module provides a small, low‑voltage solution for presence detection, edge or line sensing, and simple proximity measurements. The sensor integrates an infrared emitter and a phototransistor receiver on a compact PCB, allowing straightforward connection to common microcontrollers and development boards.
Advantages
The module offers a compact footprint and low supply voltage that makes it suitable for space‑constrained projects and battery‑powered systems. Its single‑channel design simplifies wiring and programming, while the integrated emitter and receiver reduce component count and assembly time. The board is compatible with 3.3V and 5V logic levels, enabling direct interfacing with a wide range of microcontroller platforms.
Suitable for
Line or edge detection in small robotics projects
Simple proximity sensing for object presence
Microcontroller experiments and educational kits
Automation tasks requiring low‑voltage reflective sensing
Key specifications
Number of channels: 1
Supply voltage: 3.3–5 V DC
Module dimensions: 31 × 15 mm
Detection principle: infrared reflection (IR emitter and phototransistor)
Output type: digital/analog depending on module variant or wiring (check module markings)
Typical applications: proximity, line following, edge detection
How to use
Connect the module power pins to a stable 3.3–5V supply and common ground with your controller. Attach the module output to a digital input or analog input on the microcontroller according to the desired readout method. Place the sensor facing the target surface and adjust distance for reliable reflection—typical operating range is short, a few millimetres to several centimetres depending on surface reflectivity. Use simple thresholding or calibration routines in firmware to distinguish reflected signal from background. If the module includes an onboard potentiometer or trim, adjust it to set sensitivity and switching point.
Usage recommendations
For consistent detection, orient the sensor perpendicular to the target surface and avoid strong ambient infrared sources (direct sunlight or heat lamps). Test with the actual surface materials to calibrate sensitivity; highly reflective or dark matte surfaces may require different sensor distances. When used in battery‑powered applications, ensure stable supply voltage and consider adding decoupling capacitance near the module power pins.
