SparkFun Proximity Sensor Breakout – VCNL4040 (Qwiic)
The SparkFun VCNL4040 Qwiic breakout integrates a proximity sensor (PS) and ambient light sensor (ALS) for contactless object detection up to 20cm with no dead zone. It communicates via I2C (address 0x60) at 3.3V logic, making it compatible with Arduino, Raspberry Pi, and other Qwiic-enabled development platforms.
Features
- Integrated VCNL4040 sensor with IR emitter, proximity, and ambient light sensing.
- Qualitative proximity detection up to 20cm with no dead zone.
- I2C interface (address 0x60) with SMBus compatibility and low power consumption.
- Dual Qwiic connectors for solderless daisy-chaining plus standard 0.1″-spaced breakout pins.
- Filtron technology for robust ambient and background light cancellation.

The SparkFun Proximity Sensor Breakout leverages the VCNL4040 IC, a fully integrated solution combining an infrared emitter (IRED), a proximity sensor (PS), and an ambient light sensor (ALS). The PS operates on the principle of reflected infrared light, providing a qualitative measure of object distance without the dead zone common in analog IR sensors. The ALS provides digital ambient light level data, enabling light-sensitive system adjustments.
Designed for ease of integration, the board features the Qwiic connector system for plug-and-play I2C connectivity, eliminating the need for soldering. A parallel operational structure allows the ALS and PS to function simultaneously, providing concurrent environmental and proximity data for responsive system control in automated applications.
