TIOPT3001
Overview
The OPT3001 is a digital ambient light sensor (ALS) that measures the intensity of light as visible to the human eye. It features a precision optical filter that provides strong infrared rejection, allowing the sensor to maintain accuracy regardless of the light source. With a measurement range from 0.01 lux to 83k lux and a high-speed I2C interface, it is designed for systems that require automatic backlight adjustment or environmental lighting control.
Why Choose This Part
The sensor features an integrated spectral filter that closely matches the human eye's photopic response, eliminating the need for complex manual calibrations across different light sources. Its extremely low power consumption of 1.8 microamps active and 0.3 microamps shutdown makes it ideal for battery-operated devices. Additionally, the 23-bit effective dynamic range and automatic full-scale setting simplify software implementation by removing the need for manual range switching.
Applications
Key Specifications
Getting Started
To evaluate the sensor, the OPT3001EVM evaluation module can be used with the TI MSP430 LaunchPad. For custom firmware development, engineers can interface via I2C at supply voltages between 1.6V and 3.6V, utilizing the interrupt pin to wake the host MCU only when light levels cross defined thresholds.
