### Constructor
### Constructor
- **Max44009(uint8_t address, uint8_t dataPin, uint8_t clockPin)** Constructor with dataPin (sda) and clockPin (scl) for ESP32 and ESP8266.
- **Max44009(uint8_t address, begin = Boolean::True)** Constructor for other boards e.g. UNO.
- **Max44009(begin = Boolean::True)** Constructor with default I2C address 0x4A == 74.
- **void configure(uint8_t address, TwoWire \*wire, begin = Boolean::True)** Change I2C interface and address.
- **Max44009(const uint8_t address = MAX44009_DEFAULT_ADDRESS, TwoWire \*wire = &Wire)** Constructor.
Optional address and optional I2C interface.\
- **bool isConnected()** returns true if the device address configured is available on I2C bus.
NOTE: The user must call **Wire.begin()** or **Wire.begin(SDA, SCL)** in **setup()**.
### Basic
- **float getLux()** read the sensor and return the value in LUX. If the value is negative, an error has occurred.

to an Arduino UNO 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 ;)
Pull ups on I2C bus are recommended.
