GY-30 BH1750 Digital Ambient Light Intensity Sensor Module

The GY-30 BH1750 is a digital Ambient light intensity sensor module that uses the BH1750FVI IC from ROHM Semiconductor. GY-30 BH1750 has a measuring range of 0-65535 lux and can be used to measure the intensity of light in a variety of applications.

GY-30 BH1750 is a digital ambient light sensor that communicates via the I2C bus. It outputs luminosity measurements in lux, the SI unit for measuring light. It can measure a minimum of 1 lux and a maximum of 65535 lux.

The BH1750 digital light intensity sensor module is a 16-bit digital ambient light sensor developed by Rohm Semiconductors which can accurately measure the light intensity over a wide range. It has a breakout board that consists of the BH1750 sensor along with a 16-bit analog to digital converter (ADC). This makes it easy to interface the sensor with a microcontroller or other electronic device.

Illuminance (measured in LUX) is the total luminous flux incident on a surface, per unit area. It is a measure of how much the incident light illuminates the surface. The sensor output can be accessed through an I2C interface. It can measure ambient light intensity and the measurement unit is Lux. Interfacing this module with Arduino is quite easy.

The BH1750 Ambient Light Sensor has a measuring range of 1-65535 lux and an accuracy of ±20%. It also has a response time of 100ms. The breakout board provides a number of features that make it easy to use the sensor, including:

The BH1750 digital light intensity sensor module communicates with other devices using the I2C interface and gives an output in LUX. LUX is the unit of light intensity. The sensor uses an I2C interface due to which you can easily interface it with microcontrollers. It provides an accurate value and high resolution.

GY-30 BH1750 Digital Ambient Light Intensity Sensor Specifications : –

The BH1750 light intensity sensor module has an input voltage of 2.4V to 3.6V. It is typically powered by a 3.3V supply, but can also be powered by a 5V supply. If you are using a 5V supply, you will need to use a voltage regulator to step down the voltage to 3.3V.

The BH1750 sensor has a built-in 3.3V regulator, so you can use a 5V supply without the need for an external voltage regulator. However, if you are using a 3.3V supply, you can connect the sensor directly to the supply without the need for a regulator.

The input voltage of the BH1750 sensor is important to consider because it can affect the accuracy of the sensor’s measurements. If the input voltage is too low, the sensor may not be able to measure the light intensity accurately. If the input voltage is too high, the sensor may be damaged.
