Ambient Light Sensor for PINE64
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.
