Button-Adjustable IR Proximity Sensor with Real-Time Feedback (0-200cm)

The Button-Adjustable IR Proximity Sensor is a rugged diffuse-reflection optical sensor designed for distance detection up to 200 cm. Featuring onboard tool-free push-button calibration, an integrated status LED, and full IP67 ingress protection, it is ideal for makers and engineers building outdoor robotics, smart security systems, and automated industrial machinery.

Tool-free onboard button calibration

Set the detection threshold anywhere from 0 to 200 cm instantly using the integrated push-button without needing screwdrivers or software adjustments. An onboard LED status indicator provides immediate real-time feedback during setup and active operation.

Diffuse reflection optical sensing

The sensor uses active infrared diffuse reflection to detect when an object or person enters the sensing beam. It switches state immediately upon detection and resets as soon as the target moves out of range.

Narrow cone angle for clutter rejection

A focused 30° to 40° conical detection field reduces false triggers from surrounding walls and obstacles. This makes it well suited for navigation in narrow corridors, automated mailboxes, and warehouse robots.

IP67 weather-sealed enclosure

Engineered for harsh indoor and outdoor environments, the sensor features an IP67 waterproof rating with an operating temperature range of -10°C to 60°C. It reliably resists moisture, dust, and cold conditions.

Simple 5V active-high interface

Powered by a standard 5V supply, the unit provides an active-high digital switch output. This makes it directly compatible with Arduino, microcontrollers, and standard digital logic circuits.
