Description
Instruction:VEML6035 is a 16-bit low-power, high-sensitivity CMOS operating ambient light sensor through simple I2C commands. The sensor has an active interrupt function. Trigger to remove the load on the host outside the threshold window setting. The average active power consumption is about 300uW.VEML6035 includes a photodiode, amplifier and analog / digital circuit in a single chip. The sensor has excellent temperature compensation ability to keep the output stable under temperature changes and its refresh rate setting does not require external RC low recitation filtering. There is a programmable shutdown mode to reduce the current consumption to 0.5uA.
Parameters:
Working voltage: 1.7 ~ 3.6V (recommended 3.3V)Communication connection: 12C connection (up to 400KHz)Operating temperature: -25 ~ 85 ?Resolution: 16 bitsFlicker noise suppression: 100Hz and 120HzLens transmittance: 0.0004 lux / bit

Typical application circuit:
VEML6035 has a fixed slave address for host programming and access selection. The predefined 7-bit I2C bus address is set to 0100001 = 0x29. The least significant bit (LSB) defines the read or write mode. Correspondingly set the bus address and 01010010 = 52h when writing, 01010011 = 53h when reading. Module C has a pull-up resistor, so the user does not need to pull it up again.
