TSL2561 is an optical-to - digital converter that converts light intensity into digital signal output with direct I2C connection or SMBus interface . Each device is connected to a bandwidth of a photodiode and an infrared responsive photodiode on a separate CMOS integrated circuit, which has the ability to provide near - adaptive response to a 20bit dynamic range . The two integrated ADCs convert the photoresist current into a digital output, which represents the measurement of the luminosity of each channel. This digital output can be S a microprocessor input.
TSL2561 is TAOS company launched a high-speed, low power, wide range, programmable and flexible configuration of the light intensity digital conversion chip. The chip can be widely used in various types of display monitoring, the purpose is in the changing lighting conditions, making the display to provide the best display brightness and minimize power consumption; can also be used for street lighting control, safety lighting And many other occasions. The main features of the chip are as follows:
1. Programmable configuration of the light intensity of the upper and lower threshold, when the actual light intensity exceeds the threshold given the interrupt signal;
2. Digital output meets the standard SMBus (TSL2560) and I2C (TSL2561) bus protocols;
3. Analog gain and digital output time Programmable control;
4. In low power mode, the power consumption is only 0.75 mW
5. Automatic suppression of 50 Hz / 60 Hz illumination fluctuations.
Description: The TSL2561 Luminosity Sensor Breakout is a clear light sensor which has been a flat response across most of the visible spectrum. The simpler sensors, the TSL2561 measures both infrared and visible light to the measured body of the human eye. And because the TSL2561 Is an differential sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both small and large amounts of light by changing the integration time.
The TSL2561 is capable of direct I2C communication and is able to to target specific light ranges from 0.1 - 40k + lux easily. Additionally, the TSL12561 contains two laminated analog-to-digital converters (ADC) that integrate experiences from two photodiodes, common. Requires a supply voltage of 3V and a low supply current max of 0.6mA.
