# SIM7070G (Component)

## Description

Ambient Light Sensor with I²C Digital Output – Ultra\-low\-power digital ambient light sensor designed for smartphones, tablets, LCD/OLED backlight control, IoT devices, smart home products, industrial automation, consumer electronics, and embedded light\-sensing applications\. The ROHM BH1750FVI\-TR measures ambient light over a 1 lx to 65,535 lx range with 1 lx resolution and provides direct lux readings through an I²C interface, eliminating the need for complex optical calculations\. It features 16\-bit measurement resolution, high sensitivity to visible light, 50 Hz/60 Hz light\-noise rejection, and programmable measurement modes \(continuous and one\-time\)\. Operating from a 2\.4 V to 3\.6 V supply, it consumes only 120 µA typical during measurement and 0\.01 µA typical in power\-down mode, making it ideal for battery\-powered systems\. Packaged in a compact 6\-pin SMD \(SOP\-6\) package, it operates over a −40°C to \+85°C temperature range\.
