Optical Sensors - Ambient Light, IR, UV Sensors

The SI1142-M01-GMR is a high performance, compact Ambient Light Sensor (ALS), Infrared (IR), and Ultraviolet (UV) optical sensor module. This package includes a monolithic CMOS chip containing a wide photodiode array plus associated analog, logic, and communication circuitry. With its tiny design, it is able to operate in a variety of environmental conditions including bright sunlight, low light, and even darkness. The device also provides accurate, consistent measurements of both visible and non-visible light.

The SI1142-M01-GMR has a full-spectrum light response from visible to near IR wavelengths. This allows the device to detect and measure a range of different light conditions from normal indoor lighting to outdoor sunlight. It is ideal for applications that require the measurement of sunlight or sunlight variations such as ambient light sensors or light meters. The SI1142-M01-GMR can also be used in systems to measure/monitor lighting levels or as a car auto-following and off-road warning system.

The SI1142-M01-GMR operates using a separate voltage supply and an I²C serial communication interface. It works by detecting and measuring the intensity of the incident light on the photodiode array. The individual photo-diodes are located in columns and rows across the device. The data is converted to a digital signal before being sent over an I²C. The output of this signal will depend on the intensity of the incident light. For example, in low light conditions, the sensor will deliver a high-level signal. Conversely, in bright conditions, the sensor will deliver a low-level output signal.

The SI1142-M01-GMR is designed to be a cost-effective, yet reliable, optical sensor solution. In addition, the device has a low power consumption that makes it appealing to applications where preserving battery power is important. Further features include a programmable response time, a wide range of operating temperatures, and easy integration with other light sensors and I2C compatible devices.

The SI1142-M01-GMR is a useful tool for any application that requires the measure of light intensity. It is an excellent sensor for use in a variety of environmental settings and applications, with its tiny design and wide range spectra. Whether it is used for a light meter in a research lab or a car auto-following system, the SI1142-M01-GMR is a reliable and cost-effective solution.
