GY-30 BH1750FVI Module Digital Light Intensity Illumination Sensor

The GY-30 BH1750FVI module is a digital light intensity sensor that measures illumination directly in lux. The BH1750FVI chip has a built-in 16-bit converter and an I2C interface, so you get ready-to-use readings with no analog maths, and its spectral response is close to that of the human eye.

GY-30 BH1750FVI Specifications

• Sensor: BH1750FVI ambient light sensor

• Resolution: 1 lx in high-resolution mode (0.5 lx in mode 2)
• Supply voltage: 3–5 V
• I2C address: 0x23 (ADDR low) or 0x5C (ADDR high)
• Pins: VCC, GND, SCL, SDA, ADDR

GY-30 BH1750FVI Applications

• Automatic screen and LED brightness control
• Measuring light for plants, greenhouses and grow lights
• Smart lighting and home automation
• Light meters and school physics experiments

What's in the Box

• 1 × GY-30 BH1750FVI light sensor module

Tip: On an Arduino Uno connect SDA to A4 and SCL to A5, then use the BH1750 library. Leave ADDR unconnected or tied to GND for address 0x23, or connect it to VCC so two sensors can share one bus.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
