GY-302 BH1750 Light Intensity Sensor Module — I2C, 3V to 5V
The GY-302 uses the same BH1750 chip as the GY-30 in a slightly different PCB layout, measuring ambient light from 0 to 65535 lux over I2C with 1 lux resolution in high-resolution mode. It is pin-compatible with the GY-30 and uses the same libraries. Both modules are functionally equivalent — the GY-302 is simply a different board revision of the same BH1750 sensor.
- BH1750 ambient light sensor — 0–65535 lux, 16-bit
- 1 lux resolution in high-resolution mode
- I2C interface — address 0x23 or 0x5C
- 3.3V–5V supply
Best for
Auto-brightness displays, smart lighting systems, grow light controllers, greenhouse monitoring, and any project needing calibrated lux readings over I2C.
