Optical Sensors – Ambient Light, IR, UV Sensors

ISL29009IROZ-T7 is an infrared ambient light and optical microsensor manufactured by Intersil. This device is based on a double-integrating architecture, which enables the precise detection of both IR and visible light for any indoor or outdoor environment. It is an ideal sensor to use in applications that require detection of light in a wide range of light levels, such as lighting control, UV exposure measurement, solar cell panel monitoring, and battery voltage measurement.

Overview

ISL29009IROZ-T7 is a low power, low-voltage, single-supply integrated ambient light and infrared microsensor. This device is made with an integrated broad-spectrum photodiode and a high-gain transimpedance amplifier. It has an integrated Field-Effect Transistor (FET) switch that enables the integration of large area photodiodes on the PIN diode to allow very high sensitivity to incident light. This device can operate at voltages as low as 1.8V and supply currents as low as 2mA, making it ideal for applications such as power banks and solar cell panels.

Features

ISL29009IROZ-T7 has several features that make it an invaluable asset in any system that requires optical power measurement. It has a 0 ° to 120 ° viewing angle with a maximum response time of 2ms for full-scale range. This device is also designed to be insensitive to near and far infrared radiation. Additionally, ISL29009IROZ-T7 is immune to power supply noise, making it a reliable solution for applications with high fluctuation in power supply voltage.

Application Fields

ISL29009IROZ-T7 is suitable for applications that need exhaustive optical power measurement such as lighting control, UV exposure measurement, solar cell panel monitoring, and battery voltage measurement. This device is also suitable for integration in remote-controlled toys requiring a light sensor for location, or low-power speakers that require a light sensor for use in the dark.

Working Principle

ISL29009IROZ-T7 operates on the principle of photoelectric conversion, where the incident light on the PIN diode generates a readable current that is proportional to the intensity of the light. The current generated is then amplified by the transimpedance amplifier circuit, and the voltage output is generated, which can be converted into a digital reading. The output is highly linear at a wide range of light levels, which makes this device ideal for precise optical power measurement.

Conclusion

ISL29009IROZ-T7 is an affordable and reliable infrared ambient light and optical microsensor solution aptly suited for applications requiring precise detection of IR and visible light, such as lighting control, UV exposure measurement, solar panel monitoring, and battery voltage measurement. This device provides a highly linear output with a wide range of light levels, helping to accurately detect the amount of light and accurately control indoor or outdoor environment.
