# ISL29125 RGB Light Sensor

**Type:** Product page · **SKU:** SEN-12829 · **Brand:** [Sparkfun](https://core-electronics.com.au/brands/sparkfun-australia)
**Page:** https://core-electronics.com.au/isl29125-rgb-light-sensor.html ([markdown](https://core-electronics.com.au/isl29125-rgb-light-sensor.html.md))

If you’ve had ideas for a project that depends on the ability to sense different spectrums of visible light and react based on those measurements, the ISL29125 breakout board may be just what you need. The ISL29125 breakout board makes it very easy to sense and record the light intensity of the general red, green, and blue spectrums of visible light while rejecting IR from light sources. You can then use these sensor readings for the purposes of logging and finding patterns, or creatively calculate and make control decisions in your electronic projects.

## Pricing

- **Price:** $19.75 (inc GST) — $17.95 AUD, exc GST
- **Quantity discounts:** 5+ $17.42 (exc GST) · 25+ $17.05 (exc GST) · 100+ $16.34 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 31 and Sep 04.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN-12829:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/SEN-12829:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

If you've had ideas for a project that depends on the ability to sense different spectrums of visible light and react based on those measurements, the ISL29125 breakout board may be just what you need. The ISL29125 breakout board makes it very easy to sense and record the light intensity of the general red, green, and blue spectrums of visible light while rejecting IR from light sources. You can then use these sensor readings for the purposes of logging and finding patterns, or creatively calculate and make control decisions in your electronic projects.

Each pin from the ISL29125 has been broken out to allow you to interface with it, SDA, SCL, 3.3V, GND, and even an optional INT pin is available for use. The ISL29125 Light Sensor operates at 3.3V but if you plan on using this chip with a 5V microcontroller make sure to use a logic level converter.

**Dimensions:** 18.4mm x 17.2mm x 2.4mm (0.7" x 0.6" x 0.09")

**Features:**

- Operating Voltage: 3.3V
- Operating Current: 56µA
- Selectable Range
- I2C (SMBus compatible) Output
- ADC Resolution 16 bits
- SCL, SDA, INT, 3.3V, & GND Pins Broken Out
