Descripción
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, which triggers the elimination of the load on the host outside the threshold window setting. The average active power consumption is about 300uW.VEML6035 contains a photodiode, amplifier and analog / digital circuit in a single chip. The sensor has excellent temperature compensation capability to maintain stable output under temperature changes and its refresh rate setting does not require external RC low-pass filtering. There is a programmable shutdown mode to reduce the current consumption to 0.5uAProduct Parameters:Operating voltage: 1.7-3.6V (recommended 3.3V)Communication interface: I2C interface (up to 400KHz)Operating temperature: -25-85 degreeResolution: 16 bitsFlicker noise suppression: 100 Hz and 120 HzLens transmittance: 0.0004 lux / bitPin Description:VCC: power supply +GND: groundINT: Interrupt pinSCL: I2C serial clock lineSDA: I2C serial data line
Schematic Diagram:
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, the bus address is set to 01010010=52h when written, and 01010011=53h when read. The IIC interface of the module has a pull-up resistor, so the user does not need to pull it up again.
