I2C driver for BH1750 light sensor


Component: BH1750

  • This component will show you how to use I2C module read external i2c sensor data, here we use BH1750 light sensor(GY-30 module).
  • BH1750 measurement mode:
    • one-time mode: bh1750 just measure only one time when receieved the one time measurement command, so you need to send this command when you want to get intensity value every time
    • continuous mode: bh1750 will measure continuously when receieved the continuously measurement command, so you just need to send this command once, and than call bh1750_get_data() to get intensity value repeatedly.


  • Bh1750 has different measurement time in different measurement mode, and also, measurement time can be changed by call bh1750_change_measure_time()
