Gravity: I2C VEML7700 Ambient Light Sensor (0~120Klx) - DFRobot - SEN0228

  • VEML7700 is a high accuracy ambient light digital 16-bit resolution sensor. It includes a high sensitive photo diode, a low noise amplifier, a 16-bit A/D converter and supports an easy to use Gravity I2C interface. It outputs a digital signal directly and no need for complicated calculations.
  • This is a more accurate and easier to use version of the simple photo resistor which only outputs a voltage that needs to be calculated in order to obtain meaningful data. The data which is output by this sensor is directly output in Lux (Lx). When objects which are lighted in homogeneous get the 1 lx luminous flux in one square meter, their light intensity is 1lx.
  • Sometimes to take good advantage of the illuminant, you can add a reflector to the illuminant. So that there will be more luminous flux in some directions and it can increase the illumination of the target surface.

PINE64 AMBIENT LIGHT SENSOR MODULE

PINE64 AMBIENT LIGHT SENSOR MODULE

  • Ambient Light Sensor for PINE64
  • Measures 30mm x 26mm

  • Approximates Human Eye Response
  • Programmable Interrupt Function allow user defined upper/lower limit trigger threshold

Measures 30mm x 26mm
Base on TAOS/AMS TSL2561T I2C Light Sensor
Approximates Human Eye Response
Programmable Interrupt Function allow user defined upper/lower limit trigger threshold
Automatically rejects 50/60Hz lighting ripple
Build with 2 channel of photodiode/ADC to allow more accurate calculation of light intensity (in Lux)
Can support up to 3pcs of sensor in the same I2C channel
On board 3.3V regulator
2pcs of XH 5pin 2.54 mm pitch connector to allow daisy chain of multiple I2C sensor

Each device combines one broadband photodiode (visible plus infrared) and one infrared-responding photodiode on a single CMOS integrated circuit capable of providing a near-photopic response over an effective 20-bit dynamic range (16-bit resolution). Two integrating ADCs convert the photodiode currents to a digital output that represents the irradiance measured on each channel. This digital output can be input to a microprocessor where illuminance (ambient light level) in lux is derived using an empirical formula to approximate the human eye response.
