BH1750FVI
Overview
The BH1750FVI is a digital ambient light sensor with a 16-bit resolution and a measurement range of 1 to 65,535 lux. It features a built-in ADC and I2C interface, providing direct digital output in lux without requiring complex external calculations. The sensor is designed to mimic the spectral response of the human eye and includes a 50Hz/60Hz light noise rejection function to ensure stable readings under artificial lighting.
Why Choose This Part
It offers high precision with minimal influence from infrared radiation and requires no external components for operation. The sensor supports two different I2C slave addresses (ADDR terminal), allowing multiple units on the same bus, and its 1.8V logic compatibility simplifies interfacing with modern low-voltage microcontrollers.
Applications
Key Specifications
Getting Started
Engineers can quickly evaluate this sensor using various low-cost breakout boards available through common prototyping channels. Implementation is straightforward using standard I2C libraries; the device operates between 2.4V and 3.6V and features a Power Down mode to reduce current consumption to 1uA during idle periods.
