This is the BH1750 16-bit Ambient Light Sensor from Rohm. Because of how important it is to humans and most other living things, sensing the amount of light in an environment is commonplace to get started when learning to work with microcontrollers and sensors. It’s a small, capable and inexpensive light sensor that you can include in your next project to add the detection and measurement of light.

The BH1750 provides 16-bit light measurements in lux, the SI unit for measuring light, making it easy to compare against other values like references and measurements from other sensors. The BH1750 can measure from 0 to 65K+ lux, but with some calibration and advanced adjustment of the measurement time, it can even be convinced to measure as much as 100,000 lux!

Sensors tend to come in small packages and the BH1750 is no different.

Packaged on a PCB in our STEMMA QT form factor, the BH1750 comes integrated with a voltage regulator and level shifting circuitry to allow it to be used with 3.3V devices, like a Feather M4 or Raspberry Pi, or 5V devices, such as an Arduino.
