GY-30 BH1750 Digital Light Intensity Sensor Module
The GY-30 BH1750 Digital Light Intensity Sensor Module is an I2C ambient light meter built around the Rohm BH1750FVI chip, which reports brightness directly in lux instead of a raw analog value. When you compare the GY-30 BH1750 price in Bangladesh against ordinary LDR modules, the reason makers prefer it becomes obvious — a 16-bit digital reading from 1 to 65,535 lux with no calibration headache. IoT builders and engineering students buy the BH1750 module in Bangladesh for automatic lighting control, weather stations, plant growth monitors, and lux-meter projects on Arduino or ESP32. An onboard 3-5V friendly design makes it a drop-in sensor for both 5V and 3.3V systems.
Key Features:
• BH1750FVI digital ambient light sensor with 16-bit resolution
• Measures from 1 lux up to 65,535 lux — from dim rooms to direct sunlight
• Outputs lux values directly over I2C, no analog calibration required
• I2C address selectable (0x23 or 0x5C) via the ADDR pin for multiple sensors
• Runs from 3V to 5V supply, safe with Arduino and ESP32 alike
• High-resolution mode resolves down to 0.5 lux steps for precise readings
• Compact breakout with mounting holes for easy installation in enclosures
