It is designed for qualitative sensing: detecting whether an object is present within range and whether it is getting closer or moving farther away, rather than reporting a precise millimetre distance.The board keeps the interface streamlined for its compact size. Only the VCNL4040 interrupt pin is broken out, while power and all other signals are routed through the Qwiic connector. It can detect right up to the sensor face, avoiding the blind zone found on many older proximity sensors.Alongside proximity sensing, the VCNL4040 includes an ambient light sensor for measuring lux and environmental lighting conditions. It suits applications such as touchless controls, gesture or collision detection, screen brightness adjustment, and automatic lighting.Connection is via the Qwiic Connect System, so no soldering is required for compatible setups. SparkFun documentation and software support includes a schematic, KiCad files, hookup guide, VCNL4040 datasheet, Arduino Library and Python Package, and the board is compatible with OpenLog Artemis and DataLogger systems for no-code logging.Features:Infrared Emitter (IRED): Integrated infrared emitter for proximity sensing.Proximity Sensor (PS): Detects object presence and relative movement within range.Ambient Light Sensor (ALS): Measures lux and environmental lighting conditions.Qwiic Connect System: No soldering is required to connect the Micro VCNL4040 board to the rest of your system.No-code logging: Compatible with SparkFun OpenLog Artemis and DataLogger systems for automatic detection, scanning, configuration and logging.Qwiic daisy-chain use: Works alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.Specifications:Range: ~0cm to 20cm (Qualitative detection)Dead Zone: None (Reads up to the sensor face)Operating Voltage: 3.3VI2C Address: 0x60 (Fixed)*Qwiic Micro Form Factor: 0.75in x 0.30inQwiic Connector: 1x Qwiic ConnectorDimensions: 0.75in. by 0.30in. (or 24.65mm by 7.62mm)Technical Note: The I2C address of the VCNL4040 is hardware-defined. To use multiple sensors on a single bus, you will need a multiplexer like the Qwiic Mux Breakout.Please note this board has only a single Qwiic connector, making it best suited to compact builds, use with a Qwiic Multiport, or the end of a Qwiic chain. **Product Type:** Proximity Sensor ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDibYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--516b0a0fa7ac0211bb0992333a5023b3b96c3270/30161-Proximity-Sensor-Micro-Feature.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDirYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--a63978e8144be539056f3b4c4e39fa1c2b509f63/30161-Proximity-Sensor-Micro-Front.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDi7YCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ad9a31df7afe6b255730420000ceec9d8ec77830/30161-Proximity-Sensor-Micro-Back.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDjLYCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--0ce045f6904a7016491bdb74c1d4126b565b505c/30161-Proximity-Sensor-Micro-Scale.jpg) --- ## Finding & Searching Products If a part listed here isn't quite what you need, you can search Little Bird Electronics' full catalogue: - **Search by keyword:** `GET https://littlebirdelectronics.com.au/products.md?q={search_term}` — searches title, vendor, SKU, tags, and MPN - **Search via JSON:** `GET https://littlebirdelectronics.com.au/products.json?q={search_term}` — structured JSON results - **Browse by collection:** `GET https://littlebirdelectronics.com.au/collections/{handle}.json` — products in a specific collection - **Filter in-stock only:** `GET https://littlebirdelectronics.com.au/products.md?q={term}&in_stock=1` - **Individual product detail:** `GET https://littlebirdelectronics.com.au/products/{handle}.md` — full specs, pricing, stock levels, variants Search supports multi-word queries (AND logic).
