Unsoldered GY-30 BH1750FVI Module Digital Light Intensity Illumination Sensor

Unsoldered GY-30 BH1750FVI Module Digital Light Intensity Illumination Sensor

The BH1750 is a light intensity sensor that can be used to adjust the brightness of the mobile phone display and LCD displays. It can also be used to turn the headlights of cars on/off based on the outdoor lighting. The sensor uses an I2C communication protocol so that makes it super easy to use with microcontrollers. The SCL and SDA pins are for I2C.

There is no calculation needed to measure the LUX value because the sensor directly gives the lux value. Actually, it measures the intensity according to the amount of light hitting on it. The BH1750 operates on a voltage range of 2.4V-3.6V and consumes a really small current of 0.12mA. However, this module comes with voltage regulator that can accept 3.3V to 5.0VDC input. The results of the sensor do not depend upon the light source used and the influence of IR radiation is very less. There are very fewer chances of any error because the variation in measurement is as low as +/-20%.
