Product Description

BH1750FVI Digital Light Intensity Sensor Module

High-Precision Ambient Light Sensor for Arduino

The BH1750FVI is a digital ambient light sensor IC from ROHM, designed for I2C bus interface applications. This module provides direct digital output of illuminance data in lux, eliminating complex calculations and calibration.

High Resolution Measurement - Detects 1 to 65535 lux range
Direct Digital Output 16bit ADC built-in for accurate readings
Operating voltage is 3V to 5V - compatible with 5V and 3.3V systems
Use the BH1750 library from Arduino IDE Library Manager for simple integration
Max supply voltage is 3.6V for the bare IC, but modules include level shifting

Connection Guide

To Arduino:

  • VCC: 5V (or 3.3V)
  • GND: Ground
  • SCL: A5 (Uno/Nano) or SCL pin
  • SDA: A4 (Uno/Nano) or SDA pin
  • ADD: I2C address select (GND or VCC)
Connect ADD to GND for address 0x23, VCC for 0x5C
Use 4.7kΩ pull-up resistors on I2C lines
For 3.3V systems, ensure module supports voltage
Do not exceed 5V on any pin

Programming Instructions

Install BH1750 library via Arduino IDE Library Manager. The library provides simple functions for reading light intensity.

Basic setup:

  • Include Wire and BH1750 libraries
  • Initialize sensor with begin()
  • Read light level with readLightLevel()
  • Returns float value in lux

Measurement modes available:

  • High resolution mode: 1 lux resolution
  • High resolution mode 2: 0.5 lux resolution
  • One-time high resolution: Single reading
  • Low resolution: 4 lux resolution (faster)

Multiple Modes - Choose resolution vs speed

Simple Interface - One function call for reading

Works with all Arduino boards
Compatible with ESP32 and ESP8266

√ Library handles all I2C communication

√ Returns float value in lux

√ Calibration support included

Troubleshooting

No readings:

  • Check I2C connections (SDA, SCL)
  • Verify power supply voltage
  • Avoid loose wiring

Inaccurate readings:

  • Check sensor position
  • Verify measurement mode
  • Avoid sensor in direct sunlight
