- Material: Metal; Model: GY-30; Core Type: BH1750FVI
- Voltage: 3-5V;
- The BH1750FVI sensor to measure the ambient lighting level. BH1750FVI is a calibrated digital light sensor IC that measures the incident light intensity and converts it into a 16-bit digital number.
- It can measure ambient light intensity ranging from 0 to 65535 Lux (L). The Lux is an SI unit for illuminance and is equal to one lumen per square meter. The BH1750FVI sensor directly gives output in Lux.
- The spectral response function of the sensor is approximately close to that of the human eye. The sensor output can be accessed through an I2C interface. The 7-bit I2C address is 0*23 if the ADDR pin is grounded, or 0*5C if ADDR is tied to VCC.
