The model SI1141-A11-YMO is a digital ambient light (ALS), infrared (IR), ultraviolet (UV) sensor which offers the advantage of integrating multiple functions into a single package. It offers both an ALS function and an IR emitter driver. The ALS measures the visible light through a silicon photodiode, which is combined with a current amplifier and a dedicated 16-bit Analog-to-Digital Converter (ADC). The IR emitter driver is able to detect the presence of an object in front of the sensor. Both functions are powered by a single voltage, thus reducing space, cost and complexity.
This type of optical sensor is increasingly used in consumer products such as cell phones, tablets, digital cameras, game consoles, and white goods, along with industrial/automotive applications such as retail kiosks and replacing existing mechanical switches.
The working principle of the SI1141-A11-YMO is based on the reception and conversion of light intensity into digital values using the integrated silicon photodiode, current amplifier and 16-bit ADC. The integrated IR emitter driver uses the generated current to regulate the power of the IR emission. This type of sensor also offers a self-calibrating feature in order to continuously adapt to changes in visible light intensity.
Finally, this industrial grade device offers a wide dynamic range and high accuracy level for a more reliable performance, while also minimizes power consumption at the same time.
In conclusion, the SI1141-A11-YMO is a complex solution that combines ALS, IR and UV functions, offering the best of digital measuring technology. With its high accuracy, wide dynamic range and low power consumption levels, it can be a great choice for many different applications.
