About this item

The SparkFun VCNL4040 IR, Ambient Light, & Proximity Sensor Breakout is a compact and versatile module designed for embedded sensing projects. Featuring the VCNL4040 chip, it offers accurate ambient light measurements and proximity detection up to ~20 cm with integrated IR LEDs. The module includes interrupt support and configurable measurement rates, enhancing responsiveness and energy efficiency. Communication occurs over I²C at 3.3 V (Qwiic connector compatible), simplifying integration into microcontroller systems without soldering. The breakout consumes low power and provides onboard capacitors for signal stability. Ideal for applications like gesture sensing, automatic screen brightness control, object detection, and interactive user interfaces.
