SEN-15177 SparkFun Proximity Sensor Breakout - 20cm, VCNL4040 (Qwiic)

The SparkFun Proximity Sensor Breakout – VCNL4040 is a compact, I²C‑based proximity and ambient light sensor designed for easy integration into your microcontroller or Raspberry Pi projects. With a detection range of up to 20 cm, this breakout board accurately senses the presence of nearby objects while also measuring surrounding light levels. Its Qwiic‑compatible connector makes hardware wiring simple and solder‑free when used with Qwiic ecosystems. Ideal for robotics, interactive installations, and automated systems, this breakout lets your device “feel” its environment with precision and reliability.

Key Features:

• Proximity Sensing up to 20 cm – Detect objects and motion within a useful mid‑range.
• VCNL4040 Sensor Chip – Combines a proximity detector with an ambient light sensor on one package.
• Ambient Light Measurement – Reads surrounding light levels for adaptive behaviours or lighting control.
• I²C Interface (Qwiic Compatible) – Easy plug‑and‑play connectivity with microcontrollers and SBCs via Qwiic.
• Compact Breakout Board – Small footprint makes it ideal for compact builds and embedded designs.
• Wide Voltage Range Support – Operates from standard logic levels (compatible with 3.3V and 5V systems with Qwiic).
• Library Support & Example Code – Works with popular Arduino and Raspberry Pi libraries to get you started quickly.
• Solder‑Free Qwiic Header – Simple and clean prototyping without soldering.
