BH1750 module is a digital ambient light sensor, IIC I2C communication. Good for arduino light detection. It is a
light intensity sensor breakout board with a 16 bit AD converter builtin which can directly output a digital signal, there is no need for complicated calculations. This is a more acurate and easier to use version of the simple LDR which only outputs a voltage that needs to be calculated in order to obtain meaningful data. With the BH1750 Light Sensor intensity can be directly measured by the luxmeter, without needing to make calculations. The data output by this sensor is directly output in lux (Lx). If uniformly illuminated objects receive a luminous flux of 1 lx per square meter, their light intensity is 1 lx. To get the most out of your bulb, you may be able to add a reflector to your bulb. In this way, more luminous flux is generated in several directions, which can increase the illumination of the target area.
