MAX44009 I2C LUX sensor

a.k.a. GY-49

Latest version https://github.com/RobTillaart/MAX44009

Examples

Max44009\examples\max44009_test01

  • use for e.g. UNO (use voltage convertor!)

Max44009\examples\max44009_test02

  • will not compile for UNO
  • use for e.g. ESP32

Schema breakout max44009 / GY-49


      +--------+
  VCC |o       |
  GND |o       |
  SCL |o      o| ADDRESS
  SDA |o      o| -INT
      +--------+

 ADDRESS:
 0 = 0x4A
 1 = 0x4B

 INT:
 Connect the INT pin to an pull up resistor
 0 = interrupt
 1 = no interrupt
 connect to an LED or an interrupt pin of an Arduino

Notes

Please be aware this is a 3.3 Volt device so it should not be connected to an Arduino or other 5 Volt device directly. Use a level convertor to solve this.

Do not forget to connect the address pin as you cannot read the sensor in a reliable way. As the line will float it will sometimes have the right address and sometimes not. (been there ;)
