## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0611:1` (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/SEN0611:1.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

The Gravity: Color Temperature & ALS Meter is a high-performance **light sensing device**, specifically designed to meet the needs of **professional videographers and photographers**. With precise calibration, it provides accurate measurements of color temperature and illuminance intensity. It features an illuminance measurement range of 10-10000 Lux with an error margin of (±5) + (±10%) Lux and a color temperature measurement range of 2700-6500K with an error margin of ±10% K, ensuring perfect lighting for any shoot.The sensor can be controlled using [Arduino UNO development board](https://www.dfrobot.com/product-838.html), and by following the wiring diagram and sample code provided in the [tutorial](https://wiki.dfrobot.com/SKU_SEN0611_Gravity_Color_Temperature_and_Ambient_Light_Sensor#target_7), the final color temperature, illuminance, and X, Y color coordinates data can be obtained.

Photographers can use the sensor on-site to measure environmental color temperature and illuminance. It ensures that the lighting matches desired color temperature and brightness, resulting in accurate and professional photos and videos. During post-production, photographers rely on the sensor's precise data to adjust image color temperature and brightness, maintaining consistent visual style and optimizing image quality.

**Color Temperature Precise Measurement**

Color temperature is a critical aspect of lighting, measured in Kelvin (K). It describes the color characteristics of a light source based on blackbody radiation theory. This sensor converts environmental light into standard physical quantities, accurately representing the light temperature of different times of the day and weather conditions. Whether capturing the warm hues of a sunset (2000K-3000K) or the cool tones of a cloudy day (5000K and above), this sensor ensures precise calibration of lighting.

**Illuminance Intensity Precise Measurement**

Illuminance intensity measures the brightness of a light source in lux (Lux), reflecting the light flux on a unit area. This is crucial for achieving the desired brightness level in photography and videography. The sensor provides precise illuminance readings, allowing for the creation of perfect lighting setups, whether working in a brightly lit outdoor environment or a dimly lit indoor studio.

**Compact and Efficient Design, only 26mm×24mm**

With a compact size of 26mm×24mm, the sensor is suitable for installations in constrained spaces. It operates efficiently with an operating voltage range of 3.3-5V DC and a low current consumption of 2.8mA, making it ideal for power-sensitive applications.
