With library code running on your microcontroller, it can read red, green, blue and clear light levels, as well as detect how much IR light is reflected from an object in front of the sensor.The APDS9999 is considered by Broadcom to be the successor to the APDS-9960, but it does not include gesture sensing. It does add true lux sensing rather than only reporting raw light counts.Proximity sensing is reflective IR rather than time-of-flight, so it does not provide exact distance measurements. It is best for short distances of 2 inches / 50mm or less, and can detect objects up to 150mm away. A configurable interrupt pin can trigger when a specified proximity threshold is crossed or when a colour sensor threshold is exceeded.Adafruit has mounted the sensor on a PCB with a 3.3V regulator and level shifting for use with 3.3V or 5V microcontrollers. SparkFun qwiic-compatible STEMMA QT connectors are included for solder-free I2C wiring with a suitable QT cable, and an Arduino IDE guide and software library are available to get started with just a few lines of code. QT cable is not included.Specifications:APDS-9999 specifications: APDS-9999 SpecificationsRGB and ambient light sensing: RGB and ambient light sensing (RGB and ALS)Correlated colour temperature: Accuracy of correlated color temperature (CCT)Colour channels: Individual channels for red, green, blue, and infraredGreen channel: Approximates human eye response with green channelOptical coating technology: Uses optical coating technology to emulate human eye spectral responseLight source conditions: Works well under different light source conditionsLow-light sensitivity: Low-light sensitivity; operates behind darkened glassLight flicker immunity: 50 Hz/60 Hz light flicker immunityFluorescent light flicker immunity: Fluorescent light flicker immunityALS interrupt function: Programmable interrupt function with upper, lower thresholds and persists functionALS integration time: Programmable ALS integration timeALS gain setting: Programmable ALS gain settingProximity detection: Proximity detection (PS)VCSEL: 940-nm vertical cavity surface emitting laser (VCSEL)VCSEL drive current: Programmable VCSEL drive currentCrosstalk: Cancellation of crosstalkAmbient light suppression: Ambient light suppressionProximity interrupt function: Programmable interrupt function with upper and lower thresholds and persists functionPersists function: Programmable persists functionLaser eye safety: IEC 60825-1 Class 1 Laser Eye SafetyPower management: Power managementActive current: Low active currentStandby current: Low standby currentI2C interface: I2C interface compatibleI2C speed: Up to 400 kHz (I2C fast-mode)Interrupt pin: Dedicated interrupt pinA handy choice for Arduino, microcontroller and computer projects that need ambient light, colour or close-range object detection over I2C. **Product Type:** Colour Sensor ## Images - [Image 1](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDJLgCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--99096b41b432c2cf5645994eedf1bbcf761d340b/6461-00.jpg) - [Image 2](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDJ7gCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--09abfebcb661ec69a8d1e9e7b60405abe03a3f8a/6461-04.jpg) - [Image 3](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDKbgCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--ee048d6be3db47a0c4e26037033fee083e006db7/6461-01.jpg) - [Image 4](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDK7gCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--174581a420886ca55043d110d8096375072dfe0a/6461-03.jpg) - [Image 5](https://littlebirdelectronics.com.au/rails/active_storage/blobs/redirect/BAh7BkkiC19yYWlscwY6BkVUewdJIglkYXRhBjsAVGkDLrgCSSIIcHVyBjsAVEkiDGJsb2JfaWQGOwBG--2e2265e16902d8fe6142fb5b8ea6f4780e095987/6461-02.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).
