Optical sensors detect their target by capturing visible or invisible light. Ambient light, IR, and UV sensors are just three of the several types of optical sensors. In this article, we will explore the application field and working principle of the ISL29023IROZ-T7, which is an IR Optical Sensor.

Description

The ISL29023IROZ-T7 is an infrared optical sensor from Intersil Corporation. It is a low power device with an adaptive ADC and integrated IR LED driver suitable for proximity detection, heart rate monitoring and object detection/counting applications. The total package height of only 1.72 mm makes it suitable for smartphones and other mobile applications. The device features an adjustable ADC range and an LED driver allowing it to correctly detect objects in different environments with varying ambient light levels.

Features

Features of the ISL29023IROZ-T7 infrared optical sensor include:

• Low power consumption of only 0.5% (typical stand-by current)
• Integrated LED driver with linear current control
• Dynamic range of up to 2000 lux
• Programmable ADC range for ambient light and proximity detection
• LED blink frequency of up to 512Hz
• Fast response time of only 1 millisecond
• Ultra-small 1.72 mm package height

Applications

The ISL29023IROZ-T7 infrared optical sensor is suitable for several near-field sensing applications. These can include proximity detection, heart rate monitoring, object detection and counting, and ambient light level sensing or indication.

Its ultra-small package height of 1.72 mm makes it suitable for use in smartphones and other mobile applications. It can be used to reduce power consumption in certain applications as its typical stand-by current is only 0.5%. Its adjustable ADC range allows it to accurately detect objects in different ambient light levels. Finally, its fast response time of only 1 millisecond makes it suitable for applications that require rapid detection.

Working Principle

The ISL29023IROZ-T7 infrared optical sensor operates by detecting infrared radiation, mainly visible infrared radiation (VII) and near-infrared radiation (NIR). It uses an integrated Infrared (IR) LED light source and an on-chip photo diode. The intensity of light from the LED is monitored by the Photo Diode. The output of the Photo Diode is compared to a pre-set lower threshold and an upper threshold and the results are converted into logic signals. This enables detection of objects in different ambient light levels.

The ISL29023IROZ-T7 also features an adjustable ADC range which allows it to accurately detect objects in different ambient light levels. The LED blink frequency is also adjustable, with a maximum frequency of up to 512Hz.

Conclusion

The ISL29023IROZ-T7 infrared optical sensor is a low power device suitable for near-field sensing applications such as proximity detection, heart rate monitoring, object detection and counting, and ambient light level sensing or indication. It features an adjustable ADC range which enables it to accurately detect objects in different ambient light levels and has a fast response time of only 1 millisecond. This makes it suitable for many demanding applications.
