Adafruit BH1750 Light Sensor - STEMMA QT/Qwiic
Adafruit BH1750 Light Sensor - STEMMA QT/Qwiic
This is Rohm's BH1750 16-bit Ambient Light Sensor. Since it is important for humans and most other living things, detecting the amount of light in an environment is a common place to get started as you learn to work with microcontrollers and sensors. Should we increase or dim the brightness of our display to save power? What direction should your robot move to stay in an area with the most light? Is it day or night? All these questions can be answered with the help of the BH1750. It is a small, powerful and cost- effective 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 with other values such as references and measurements from other sensors. The BH1750 can measure from 0 to 65 K+ Lux, but with some calibration and extended adjustment of the measuring time, it can even be convinced to measure up to 100,000 lux! Sensors usually come in small packages and the BH1750 is no different. Not much larger than a grain of rice, this handy, light-sensing friend needs some help to be used by people who experiment and without the desire or tools of having to work with surface-mounted parts. Packed on a PCB in a STEMMA QT form factor, the BH1750 features a voltage regulator and level circuit to use with 3.3V devices such as a Feather M4 or Raspberry Pi or 5V devices such as an Arduino. Instead of working with the small contacts on the sensor, the PCB on which it is packed breaks all pins onto a standard 2.54mm pitch header. To make things easier and a bit more flexible, they've also included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus so you don't even have to solder!
