The BH1750FVI-TR by ROHM Semiconductor is a digital ambient light sensor that provides high-resolution lux measurements through an I2C interface, designed specifically for precise brightness control in applications like LCD backlighting, mobile phones, tablets, TVs, and smart lighting systems. Packaged in a compact WSOF-6 surface-mount package, this sensor simplifies integration while delivering accurate measurements over a wide dynamic range from 0.11 lux to 100,000 lux, closely approximating the human eye’s response to ambient light. It supports continuous and one-time measurement modes with low current consumption, making it suitable for battery-powered and always-on applications.
Key Features:
• I²C digital interface (up to 400kHz)
• Wide range ambient light detection: 0.11 to 100,000 lux
• Spectral response similar to human eye
• No need for complex calculations — output directly in lux
• Low power consumption: ~190µA (typical operating), 1µA (power down)
• Supports multiple resolution modes: H-Resolution (1 lx), H2-Resolution (0.5 lx), and L-Resolution (4 lx)
• Operates under low light and high brightness environments
