Digital Ambient Light Sensor Module GY-302 BH1750

Imagine a sensor that quietly monitors the light around you and helps your projects respond naturally—reducing screen glare, automating lighting, or fine-tuning plant growth settings. The “Digital Ambient Light Sensor Module GY-302 BH1750” is tailor-made for makers, hobbyists, and embedded engineers who need precise, real-time illumination data. Leveraging the powerful BH1750FVI light intensity sensor, this module offers a wide detection range, direct digital output, and simple I2C integration that lets you skip the analog conversion headache.

Key Features

• Uses the BH1750FVI chip which measures illuminance from 1 lx up to 65,535 lx (expandable to ~100,000 lx) with high resolution. Mouser Electronics+2wiki.sunfounder.cc+2

• I2C interface supports standard bus rates, two selectable addresses (0x23 or 0x5C), and supply voltage from 3 V to 5 V for easy compatibility. michiel.vanderwulp.be+1

• Low power consumption (typical ~120 µA) and automatic power-down mode, making it ideal for battery-powered or always-on applications. Wolles Elektronikkiste+1

• Broad usage scenarios from ambient light sensing in smart lighting to automation in Arduino, Raspberry Pi or other microcontroller setups.

Why Choose Our Digital Ambient Light Sensor Module GY-302 BH1750
Many basic photoresistor or analog light sensors require calibration, external components or suffer from poor accuracy. This module gives you ready-to-use, digital lux readings with minimal setup. Instead of slower, less accurate alternatives, you get direct digital output, wide range detection and easy I2C connectivity—so your project responds faster and more reliably.

Perfect For

• Makers and IoT developers creating smart lighting, plant-growth systems or ambient-aware displays.

• Embedded engineers needing a light sensor component compatible with Arduino, ESP32, Raspberry Pi or microcontroller platforms.

• Educational projects and prototyping where simplicity, accuracy and versatility are required.

• Anyone upgrading from analog light sensing to a digital solution with higher resolution and fewer setup challenges.

How It Works
Connect VCC (3 V–5 V) and GND, wire the SDA and SCL lines to your I2C bus, optionally set the ADDR pin for alternate address. The module reports lux values directly—no calibration needed. Use your microcontroller library for the BH1750FVI, read the value, and respond in code as needed (e.g., dim lights, trigger automation, record data).

Stay one step ahead of light changes with the Digital Ambient Light Sensor Module GY-302 BH1750. Ready when you are—power it up and start sensing smarter today.
